Some Thoughts on Maintenance Work

1. Some ideas about maintenance work Maintenance work falls into two major categories, fault maintenance and protective maintenance, both of which are aimed at stable operation of the equipment that has been delivered to the user. The profitability of maintenance work must also be considered.

• In principle, fault maintenance and protective maintenance are both carried out by the

one person.

• Both fault maintenance and protective maintenance involve the bringing of maintenance

parts.

• The cooperation of the user/operator is used effectively.

2. Protective maintenance work Periodic maintenance is designed to provide the user with more stable operation of the equipment and involves the periodic cleaning and replacement of replacement parts. Basic ideas on protective maintenance include:

• Adhere strictly to preventive maintenance periods.

• In a case of carrying out preventive maintenance, gain the approval of the user before-

hand.

• Don’t press preventive maintenance on the user.

3. Fault maintenance work A fault will hold up the user’s work and must be remedied quickly. The following are some basic ideas on fault maintenance:

3-1 Use the user/operator to obtain a more detailed grasp of the fault.

• Conduct a primary consultation by “inquiry sheet”, “fax” and “telephone”

• Select applicable symptoms from the trouble-shooting lists and make inquiries in

accordance with the primary consultation form. (Check error messages, check the user’s operating conditions, test again with changed settings, output test patterns, etc.)

3-2 If it is not solved by the primary consultation, take the necessary maintenance items

and make an on-site visit.

• Assemble the necessary maintenance parts from the matrix map

• At the user’s premises, first check the symptoms.

• Proceed with maintenance work in accordance with the fault tracing procedure.

• After the repair work is finished, be sure to check again by testing in accordance

with the test procedure.

3-3 If repair is not possible even though all the work has been done in accordance with

the fault tracing procedure:

• Contact the Sales Support Groups in Graphics Sales Section or Data Equipment Sales Section of the Data Imaging Operations Division.

4. The need for user/operator cooperation

! CAUTION: The user can not be compelled to do the following!

Asking the user/operator to cooperate is not a matter of having the user do the maintenance for you but it is necessary in order to have the equipment working more efficiently and for having faults rectified quickly. Actually, even when you do ask for the user’s cooperation, instead of a simple acknowledgement you will usually get doubts and quibbles such as “I’m paying for maintenance”, “I’m not familiar with the equipment” and “it only benefits the manufacturer.” However, you must try to persuade the user/operator to cooperate by explaining that doing daily inspections will give better printing quality and giving you all the fine details of a fault means that the fault will be rectified quickly.

The following explains the items you need in order to understand fault conditions in detail:

• Check error messages

• Check user’s usage conditions

• Output from diagnostic pattern

• Output from setup lists

• Retest after changing settings

• Probability of recovery by implementing daily inspections.

Precautions For Maintaining This Printer

PRECAUTION 1 Head Cleaning

Head cleaning (see REP1620) must be carried out when this printer is to be transported by truck (see CON6000) and when the following parts are to be replaced. < Replacement parts > Head, Damper, Head Cable, Cartridge Frame Assembly,

Ink Tubes

PRECAUTION 2 Head Cleaning Jig

When the head cleaning jig is to be used, fill the jig’s 100 cc bottle with at least 50 cc of cleaning fluid and use it with the cap loosened. If head cleaning is done with the cap tightened, ink will flow back into the 100 cc bottle. When you have finished head cleaning, return the remaining cleaning fluid from the 100 cc bottle to the 500 cc cleaning fluid bottle (JD-42054).

PRECAUTION 3 Printing After Initial Filling

On rare occasions, printing quality may be unstable if printing is carried out immediately after initial filling. If this occurs, switch off the power and wait for at least 30 minutes before trying to print again.

PRECAUTION 4 Thorough Waste Fluid Box Replacement

When the following tasks have been carried out, install a new waste fluid box and clear the waste fluid counter.

1. After head cleaning and initial filling.

2. When it was not possible to capture main board backup parameters.

PRECAUTION 6 Take Care When Inserting Head Cable and Y Cable

PRECAUTION 7 Ink and Cleaning Fluid Conduct Electricity

When the print head assembly, head board assembly and main board assembly have been replaced, be careful to insert the head cable and Y cable straight to the back and don’t forget to lock the connectors. (The connectors fitted with locks are J207 and J208 on the head board.) If the cables are inserted obliquely or power is applied without locking the connectors, there is a risk that the head board may be damaged and it will be impossible for ink to be ejected.

Ink and cleaning fluid will conduct electricity. If there is ink or cleaning fluid on cables or connectors when power is applied, there will be a short circuit which may lead to all sorts of damage. If there is ink on the contacts of the connector, wipe it off with alcohol or ethanol and allow to dry thoroughly before reconnecting.

PRECAUTION 5 Maintenance Unit Tubes

If you can not lower the maintenance unit cap assembly and the cap assembly and pump assembly have been replaced:

• When the two tubes from the pump assembly are being connected to the cap assembly, turn them clockwise through 45 to 90 degrees as you insert them.

How to Clean the Printer Main Unit

RJ-4100 printer should be wiped free of dirt with a dry soft cloth.

Plotting Board

Cutting Groove

Use a soft damp cloth to wipe away any paper fluff adhering to the printing board and cutting groove.

♦ The power switch of the RJ-4000 series printer should be switched off

during cleaning.

♦ Don’t use solvents such as thinners or benzene that will damage the finish. ♦ Covers that are fixed with screws contain electrical components and

must not be opened during cleaning.

♦ Paper dust which is produced when the printer is working should be

removed periodically. Make sure that it does not get blown around.

♦ Stubborn dirt that is difficult to remove may be removed with a lint-free

cloth dampened with alcohol.

CAUTION:

♦ Paper dust and fluff will accumulate with long term use and stick to

the plotting board and cutter groove and may cause printing quality and cutting performance to deteriorate. They must be cleaned periodically.

IMPORTANT:

Brush

Grid Roller

Use a soft damp cloth to wipe away any paper dust sticking to the pressure roller. Clean the grid roller with a nylon brush.

♦ Paper fluff sticking to the pressure roller and movable roller may prevent

normal feeding of the media and produce a “Skew Check Error”. They must be cleaned periodically.

IMPORTANT:

Page 19

CON5011Model Name: RJ–4100

How to Clean the Printer Main Unit

Use a cotton bud to wipe away any dust and paper fluff from the front and back paper sensor covers in two places.

Paper Sensor Cover

♦ Progressive soiling will affect the sensitivity of the sensors and faulty

detection of the media in the initial operation may cause a “Skew Check Error”. They must be cleaned periodically.

IMPORTANT:

Page 20

When a RJ-4100 Series printer is displaying “No ink” or “No cartridge”, the cartridge should be replaced or filled without delay. Also, ink cartridges should be prepared when “[YMCK] Ink Near End” is displayed.

Step 1 If “No ink” appears in the message display section, when there is no printing operation in progress, from the back of the printer, pull out the ink cartridge whose color is indicated.

Step 2 Open the new ink cartridge packet.

[YMCK] cartridge

♦ Each letter Y, M, C, K in the display indicates a color: “Y” (yellow),

“M” (magenta), “C” (cyan), “K” (black).

♦ Colors for “no ink” are expressed as colors 1 to 4.

Reference:

CON5020Model Name: RJ–4100

How to Replace Ink Cartridges

Step 3 Insert the new cartridge in the slot at the back of the printer.

Step 4 Check that the display has reverted to its permanent display.

Reference:

♦ Only specific cartridges can be used. They also have a particular place and

orientation. Be careful not to confuse the location and orientation.

♦ Don’t open the sealed package until you are ready to insert the cartridge in the slot.

If a cartridge is stored for a long period with the seal opened, the printing may be patchy.

♦ Cartridges should be used within two years of the date printed on the package.

An ink cartridge that has been mounted in the printer for two years should be replaced.

♦ A cartridge that has been mounted in the printer should be replaced within six months.

How to Replace the Cutter

Depending on the type of roll media, paper dust may build up in the cutter groove and on the cutter blade causing poor cutting. In such cases, the cutter should be cleaned or replaced or the cutter groove should be cleaned. The cutter is a consumable item. It it cuts badly, replace it.

Step 1 Switch off the power and bring the head to the center.

Step 2 Press the cutter down with your finger and rotate the arm to the front. Take out the cutter.

Wipe the cutter blade with a dry cloth or replace the cutter.

Step 3 Insert a new cutter in the hole in the head. As you push down on the cutter, restore the cutter arm over the cutter. The cutter will only go in one way.

Cutter Arm

♦ There is a spring in the cutter mounting hole. Be careful not to lose it

when you replace the cutter.

CAUTION:

♦ The cutter blade is very hard and brittle. Be careful not to knock it or

drop it.

Step 4: Return the head to the right end and switch on the power.

CAUTION:

♦ Since the life of the cutter depends on the type and thickness of the media

and the usage environment, it is recommended that a spare cutter be procured.

Reference:

The auto-cut function cannot be used with some types of recommended media. If these types of media are used, a commercial cutter (such as OLFA 30B) or scissors must be used for cutting. The types of recommended media than cannot be cut by auto-cut are:

- Indoor cloth - Yupo tac film

- Fire-resistant cloth - Yupo film

- Outdoor cloth

CAUTION:

Step 2 When the message, “Waste Fluid Tank Full” appears, pull out the waste fluid box. When the waste fluid tank is removed, the message, “No Waste-Ink Tank” will appear.

Step 3 Without tipping it up, transfer the waste fluid box to a plastic bag for disposal.

Chk Waste Ink Tank

No Waste-Ink Tank

Waste-Ink Tank Full

After has appeared, the Waste-Ink Tank Full display will appear after printing about 20 pages of A1 media (with 20% printing) or cleaning

about 40 times.

Chk Waste Ink Tank

Step 4 Insert a new waste fluid box in the printer.

Step 5 Use the [VALUE +] or [VALUE -] keys on the purple part of the operating panel to change the display to “Yes”.

Step 6 Press the [Enter] key on the purple part of the operating panel.

♦ The waste fluid box can be treated as non-combustible garbage. ♦ Don’t squeeze the absorbent sheet soaked with waste fluid or

the waste fluid may leak.

♦ Since it would be dangerous for children to lick or swallow the absorbent

sheet soaked with waste fluid, it should be disposed of promptly or kept out of the reach. If the waste fluid is accidentally touched, wash immediately with soap and water. If waste fluid gets into the eyes, wash with plenty of water and consult a physician. If it is licked, immediately gargle and wash with water. If any has been swallowed, as a matter of urgency, drink copious quantities of water and be sure to consult a physician.

♦ If the waste fluid box has been pulled out by mistake, press the enter key

when “Change Tank?: No” is displayed.

• In the case of roll paper, the media is set correctly if it moves backward and forward parallel to the marker line during media detection, and it is in the same position as it was prior to detection. However, if the position seems to be offset, it must be remounted. → Mount the media again so that it is in the same position before and after media detection.

• Are you explaining what is meant by skew and meander? Check this condition in detail during the primary consultation. Explain that skew up to the figures shown below is within the acceptable limit. Also, have the repeatability checked and explain that poor repeatability is probably caused by badly mounted media.

However, it should be explained that in the case of roll media, if the pressure is left down for a long period with the media mounted, or in an environment with sudden changes of temperature and humidity, the whole roll may not necessarily feed properly.

• In a case where the symptoms are not reproduced (no problem up to the fifth sheet then frequent skewing after remounting, etc.) the method of mounting the media may be at fault and this should be checked with the Operation Manual. → Check "Loading the media" under "Installation procedures:" in the Operation Manual.
