The method that component of needle type Printer defends and skill

[IT168 OA maintains a station]Breakdown of the head that print basically has: The head that print breaks the needle, needlework that print to encircle the burned-out, head that print and the clearance deviate between the roller that print and cable of the head that print to break a line to wait.

1. The head that print breaks a needle

The head that print breaks a needle is the breakdown with the commonnest Printer, this kind of breakdown takes the in part of total breakdown almost. The lattice that because the printing principle of Printer is,forms by ribbon of stroke of many needle that print forms a character / Chinese character. There is an injection in be like the head that print, can appear printed character / Chinese character defect delimits less. Here emphasizes those who introduce a few kinds of model to change needle method:

(1)LQ—1600K/ LQ-1900KPrinter

1) structure. LQ—1600K and LQ-1900K print a head to all be double deck hackle to list a structure, needle cent is long, two kinds short norms, root of each L 2, long shot length is 36mm, brief shot is long for 26mm. In all 24 needles divide odd even biserial. Grow a needle to be among them: 2, 6, 10, 14, 18, 22, 3, 7, 11, l 5, 19, 23; brief shot is: 4, 8, 12, l 6, 20, 24, l, 5, 9, l 3

2) changes needle method. Check program examination to give which a few needle occurrence trouble with breakdown of the head that print above all, get off next ribbon box, break up to print a Suo Dingga, hold carbon fin of the head that print from both sides (namely crust) , mention up the head that print can see connecting two flexible and compressed cable, extract cable can take out the head that print. Swab the Chinese ink before the head that print with alcohol tampon corrupt, examine whether to have the case that be short of a needle.

If break a needle, need to undertake changing a needle. The tool should get ready when changing a needle, basically have forceps, razor blade, King Kong defeat, steel rule, oilstone and print a special fixture (a kind of tool) that is used technically at disassembling to print head carbon fin. Retreat next carbon fin with special fixture, can see several structures.

the head gadarene, loose fixed position is ungual, get off lid of the copper after uppermost, can see annular 12 when distributing long shots, from the test the result distinguishs giving an injection is long shot or brief shot, count a seat that snaps long shot next, take out with forceps put aside if; still has brief shot to break a needle, continue to take out an injection, the lower part of maize copper spacer among edge of reoccupy razor blade is apart, show 12 brief shots, take out an injection with same method. Then gets off a good shot (take long shot or brief shot to inspect what change a needle and decide) , measure the length of this needle accurately with steel rule, will new needle presses the dimension of a quantity, with Jin Gang defeat has been ground (the head burr abrasion of watchful general needle) hind, insert from former position again, the rear that presses 12 needles gently points to with the hand after been change, make syringe needle once upon a time face smell, right now, should see a needle and 24 needles the needle is shown, and interval answers between each needle and needle one aperture, if the position inserts a fault, must readjust. In the meantime, after finger is unlocked each needle can instantly decreasing, make sure each needle gives an injection expedite.

Be in only after affirming brief shot reachs the designated position entirely, ability can install long shot. Adding up to copper before make the fixed position of every needle sells slot even, long shot layer fixed position aperture shuts, the examination can install long shot without aperture. Grow needle simply to be inserted according to corresponding opening position, grow a needle to come forward to explore from the rear, want to pass a few oriented chamfer, most the groovy aperture above is very easy wear go down. The 2nd aperture a little a few more difficult, want to wear the past only, needle can take advantage of an opportunity and below, reach place place very easily. Pin armature with big toe, the needle should show 1mm, representing the injection that changes is good. After been insert entirely, press lid of the copper after going up, should not have aperture, had installed claw of 3 feet fixed position, cover on carbon fin, can go up the machine test that print.

Before the test, do not install ribbon first, self check prints paper of a piece of single page, in case new needle blows broken ribbon. Reoccupy checks a program to have a test, the result is only normal, ability is used.

(2)AR-3200/AR-3200 Ⅱ / CR-3240 Ⅱ prints a head

AR-3200/AR-3200 Ⅱ / CR-3240 Ⅱ on the structure of the head that print of Printer of type of these 3 kinds of needles basic and identical, except 3 person the bounce of return spring and block of coil of drive of the needle that print are worth the needle that print different outside, other and even appearance, the needle that print is monolayer forms a structure, its print the length of the needle to be 35.2mm.

Like checking needle method to print a head with series of afore-mentioned EPSON LQ. Change a needle to undertake by the following measure:

The head that 1) will print a head is gadarene, the black that tears open next heads that print is plastic crust, get off after hand of the reoccupy after the I -shaped bolster plate of an activity breaks two metals to secure checkpost, ordinal get off armature of the back shroud, needle that print presses reed and white plastic bracket, can see the armature that shows 24 when round arranges needles that print at this moment.

2) takes out an injection with forceps (when taking an injection with forceps, the movement wants light, do not come out the nylon peg below the needle that print and return spring belt) , print from this again likewise a good shot that print gets off on the head, with firm rule exact amount produces the length of this needle, the size that new needle estimates by place, after using burr of ministry of pinhead of abrasion of King Kong file, insert from before locally again, press the armature of 24 needles gently with finger, make syringe needle from the directing in front board on show, observe whether 24 needles come out entirely.

3) answers white according to original ordinal and ordinal outfit after armature of the plastic bracket, needle that print presses reed, back shroud and fixed check, mount prints head crust, use a group + on the drive coil that the volts d.c. of 10V brings to bear on to print a needle to each groups respectively (the method prints head) with LQ series, ordinal test prints a needle every to give the flexibility of the needle and the consistency that the flight is apart from.

4) returns outfit of the head that print on former Printer, do not install ribbon first, self check prints paper of a piece of single page (in order to prevent the printing needle of new clothes ribbon hang up) hind, reoccupy prints a program of the test that break a needle to have a test, can use after the examination is regular.

2. The needlework that print encircles breakdown

Because print a movement giving an injection,be after relying on electrify of coil of drive of the needle that print, suck close or release armature and pat those who hit the needle that print. If needle drive coil is burned (open circuit) , the corresponding needle that print does not give an injection, cause the defect that print to delimit; is like short circuit of needle drive coil less consequently (puncture) , possible meeting makes whole Printer does not work.

Coil of drive of the needle that print is normal, the R×1 that uses avometer commonly blocks the method that measures its dc resistance to undertake differentiating. It is with LQ1600KPrinter below exemple introduce to change for everybody the method of coil.

Change answer to find bad coil according to fixed coil correspondence relation when coil, cut off felt to wear the isinglass that go up in coil with the penknife, reoccupy forceps and electric iron take out coil. When tearing open next bad coil, should notice not to want to touch the good coil of photograph adjacent bad, also do not want to damage bad coil further, because bad coil is possible recycle. Coil became bad usable discard as useless the good coil in the head that print is replaced, OK also oneself are circled make. The method is, after tearing open next bad coil, if coil is broken the place is outside contact place, but will break line take out, press fine line a bit coat of paint, again solder brings a foot to go up to coil can; tears open bad coil otherwise below, the enamel-insulated wire that the diameter is 0.06mm, a solder brings a foot to go up in a of coil framework, circle endure one v/LIT all over the ground even ground to be circled on framework, circle framework full, measure its resistance with avometer, be in 29 ohmic place, cut the line bring up the rear, the foot brings this thrum solder to go up in another of framework. Install the coil of foster cordial relations between countries, install what coil should notice when coil to bring a foot not to want to be touched with iron carapace photograph. Secure good coil with isinglass finally.

After the head that print fosters cordial relations between states, according to when disassembling go against order to restore the head that print.

After the needle that print and coil maintenance are over, do not be eager to switching on the mobile phone first, if print,wired circle damages in the head, it is normal to need to check the drive dynatron V1—V24 inside Printer, the periphery circuit just the same of 24 drive dynatron, so, the static state that measures every dynatron below normal circumstance is online parameter is very adjacent. Below the circumstance that cuts off the power in Printer, measure the resistance between the B—e that each drive is in charge of, C—e with avometer, can judge drive canal to whether have a problem. If there is damage in drive canal, still can burn out drive coil.

The head that print and the clearance of the roller that print are a of Printer important parameter. If have deviate, light person the influence prints the effect, the person that weigh can cause a needle, the user should take regular examination seriously to adjust.

(A kind of general " clearance " adjusts 1) method

1) general outfit takes a box to get off in chromatically of the head that print.

The fixed screw that 2) opens Printer housing and tears open frame leaving a word has frame traditional Chinese clothes the one aspect of the matter of adjusting rod of the head that print to raise.

3) is loose the fixed screw cap of adjusting rod of the head that print (adjusting rod is in with screw cap installation the word car with prejudicial belt is slippery on lever bolt, what some Printer use is screw) , dial adjusting rod of the head that print to second gear (it is flimsy position) commonly, printing head and 4 paper that print are inserted between the roller that print (make an appointment with 0.23—0.27mm thick) , slippery lever of rotational word car (the attention maintains adjusting rod to be in from beginning to end) of second gear, 4 paper that make insert can be throbbing but chafed somewhat force. At this moment, the left, medium, right place that printing roller respectively undertakes adjustment, wait for even hind, will tighten on the fixed screw cap of adjusting rod again can.

5. The maintenance of the head that print measure

(1) avoids to print a needle to direct aperture jams, printer is using 3 months or accumulative total prints above of 50 thousand character, answer the head that print to undertake cleaning with alcohol.

To easy assemble and unassemble the type head that print if for LQ1600K, DLQ-2000K, LQ—670K, AR-5400, its clean a method to have two kinds, introduce as follows respectively:

1) method one

Tear open the head that print from Printer below, its front gives a needle to be in 1—2cm to immerse in anhydrous alcohol, inspect its to pollute degree to immerse 2 hours or so.

With brush gently scrub prints a place giving an injection, or with medical injector sucks person anhydrous alcohol to aim the end on mouth giving an injection and lower end to inject for many times, till contamination abluent, next cool work can.

Good cable of the head that print and join of the head that print, the head that print does not install the word frame in Printer to go up to be taken however first in the hand (had better tear open cable of join of the head that print from word frame fall to install the head that print again, can be in so of frame left or on the right side of the word car in grabbing the head that print and getting exercise disturbs) , executive self check prints 2 minutes or so.

After self check ends, print the alcohol of a place giving an injection and contamination with pledget blot, undertake self check is printed again and suck the alcohol that is in at giving an injection and contamination, till contamination is not had on pledget till.

2) method 2

Preparation works:

Prepare a bottle of benzine with higher grade, if benzine of date or 90 aviation serves as clear lotion. If also can use anhydrous wine without afore-mentioned benzines,essence of life replaces; additional preparation a few advanced lube if sewing machine oil or horological oil.

Preparation installs the plastic roundlet box of chromatic film.

A special text document compiles in the computer, the characteristic of this file is every have a character and carriage return only all right, every character is not identical, every character when its meaning is being printed has the chance that gives an injection. Write 40-50 travel in all, save file to disk stand-by.

Unit process of cargo bandling:

Tear open the head that print from Printer below. Compressed cable is not taken, the attention does not touch cable.

In going out front of the head that print needle place to immerse to wash the chromatic box of fluid in Cheng Youqing, the attention puts an end to all igneous causes.

The text file that the editor saves file to disk above v is started print. Can see the head that print is secured to be in the first to move repeatedly locally right now, won't come up against other part, and the needle that print relapses in rule of according to character however stroke of advance and retreat. Such. Keep clear of contamination very quickly in clear lotion go out. After relapsing for many times so. Extend a person to print gently with toothpick keep clear of the contamination such as fiber between the needle. Change clean clear lotion again, clean 3 times repeatedly can.

Put the printing head after cleaning in the drying below desk lamp half hours. The attention does not leave the lamp too close, lest temperature is high.

A few lube are entered in the drop in mouth giving an injection and obliterate redundant oil stains. This job is very main, cannot oversight. Meet what give needle mouth point quickly wear away otherwise, influence service life. Install the head that print to try dozen. So far. Printer can print the character that gives clarity and image.

(2) is cleaned assemble and unassemble not easily type prints a head

DPK-8100E/8300E, DPK-8200E/8400E, DLQ-1000KOP, 4 OKI-5530SC, the printing head of the needle type Printer such as OKI—5330SC and EPSONTM-U300PB assembles and unassemble not easily, of Printer of type of this kind of needle clean a method to be as follows:

① upgrade lifts the cover board of needle type Printer, take out case of the ribbon that print, adjust lever of clearance of the head that print, make the head that print and the clearance between the roller that print are in the largest position.

② is used medical injector sucks person anhydrous alcohol, give the end on pinhole from the head that print infuse, inspect its to pollute degree to vacate pinhole immerses half hours or so in alcohol, in this one process, answer to place the paper with better water imbibition in the lower end that gives pinhole, lest do not have watery wine essence and Printer of dirty content pollution.

③ Printer puts through Power Source, mount prints paper, executive self check prints 5 minutes or so.

④ repeats measure of ② , ③ for many times, till print,the apparent trace that print is not had on paper till.

⑤ will print a blot of alcohol of place giving an injection with pledget finally, install good ribbon box, after adjusting the head that print and the clearance between the roller that print, can use normally.

2) does not print stencil with Printer as far as possible, when if must use Printer,printing stencil, want the take out of a tissue paper below stencil, fill up a good paper to print the obstruction of a transverse motion in order to reduce. Print end should clean the rubber roll that print in time with alcohol, unripe chemistry reacts and cause rubber roll in order to avoid olefin and hair of the rubber roll that print scraggly.

3)Printer should prohibit turning artificially absolutely in use process the rubber roll that print, if must turn the rubber roll that print will adjust the word of row spacing and the position of the paper that print, answer to make condition of Printer park off line undertakes adjustment again first.

4) ribbon ageing should change in time, want good with quality ribbon, in addition even the roll with often observing ribbon is agile, discovery should be handled in time unusually.

5)Printer does not close forcibly during the job machine, if should stop,print can press stop key or give out an instruction to make its quit the job with computer.

6) hurry uses the printing paper of off quality, should avoid to use multilayer the paper after paper or fold is printed.

7) buys the ribbon of quality qualification and ribbon box, must install when installation reach the designated position.

8) has adjusted the head that print and the distance between the rubber roll that print, make print the strength that the manuscript that give wants handwriting clarity namely and gives an injection to cannot pass again big.

   The armature spring that 9) notes the examination head that print is medium (or reed) stretch, if ageing should change in time.
