Precautions For Maintaining This Printer

PRECAUTION 1 Head Cleaning
Head cleaning (see REP1620) must be carried out when this printer is to be trans-
ported 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 immedi-
ately 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 Bottle Replacement
When the following tasks have been carried out,drain the waste fluid bottle.
1. After head cleaning and initial filling.

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.
PRECAUTION 6 Take Care When Inserting Head Cable and Y Cable
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 connec-
tors, there is a risk that the main board assembly may be damaged and it will be
impossible for ink to be ejected.
PRECAUTION 7 Ink and Cleaning Fluid Conduct Electricity
Ink and cleaning fluid will conduct electricity.
If there is ink or cleaning fluid on the connectors of the head or head cables 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.
