7-2-1. Procedure for Solving the Print Quality Problems
Follow the procedure (Step 1 to 7) below until the print quality problem is solved.
<Note>
The following steps are shown with CMYK Print Heads and do the same in case of White Print Heads.
Step 1: Confirm the amount of remaining Ink in the Ink Cartridge and execute Normal Cleaning.
Head Cleaning, with flushing fresh ink, can solve most of print quality problems. Check the nozzles by test printing
of Nozzle Check Pattern (see "7-2-3. Checking Print Quality with Nozzle Check Pattern ") first and execute
Normal Cleaning to the Print Head concerned (see “7-2-2. Cleaning the Print Heads / Using the Head Cleaning
Button”) Repeat the Normal Cleaning a few times. and check again by printing Nozzle Check Pattern. If the
problem is not solved, go on to the next step.
<Note>
It is very important the machine is used in an environment as specified. Use a humidifier to keep the humidity
up to 45% to keep print quality.
Your printer automatically cleans its Print Heads every 24 prints; however more frequent Print Heads cleaning
may need to be done depending on the environment. In this case, change the Auto Head Cleaning frequency
(see “7-2-5. Changing the Auto Cleaning Setting”).
Step 2: Replace Wiper Cleaners and clean around the Print Heads, and replace the M/Y Filter.
The Wiper Cleaner absorbs waste ink carried by the Wiper Blade. If Wiper Cleaner cannot absorb waste ink any
more, the dirty Wiper Blade wipes the Print Head Nozzles again, and this should cause misfiring or damage the
Print Head. Replace the Wiper Cleaner regularly and clean the Wiper Blades and caps. Check if it is too dirty to
wipe off the waste ink when you cannot solve mis-firing by Nozzle Cleaning.
How to Check:
(1) See "6-1-2. Replacing the Wiper Cleaner and Cleaning the Caps / Wipers" and select [Maintenance] >
[Maintenance Parts Exchange] of the menu. If you find the warning [Exchange Filter (M or Y)], exchange the
Filter to the new one by referring to “6-1-8. Replacing the CMYK Filter”.
(2) Replace Wiper Cleaners as well as cleaning Wiper Blades and Caps. replace Flushing Plate Sponge and
Flushing Plate Felt too because the dirty surface of the Flushing Plate felt may give dame to the Print Head
Nozzles. See "6-1-3. Replacing Flushing Plate Sponge and Flushing Plate Felt".
(3) Confirm the inside of the printer and clean if necessary. See "6-1-6.Cleaning the inside of the printer and
restart".
<Note>
Do not tilt the Wiper Cleaner, ink may get on your hands or clothing.
(4) Check the Wiper Cleaner, and if it is heavily soiled, replace it using the Cap Cleaning Kit (see “6-1-2.
Replacing the Wiper Cleaner and Cleaning the Caps / Wipers”). If the Wiper Cleaner is not heavily soiled, go
on to the next step.
Step 3: Check the ink tubes and execute Powerful Cleaning.
Open the Front Cover with both hands until it is locked with the stopper and check the ink tube inside if there is
any "empty" air space longer than 5 mm. If so, push the Stop Lever to release the lock when you close the Front
Cover with both hands and turn ON the printer, execute Powerful Cleaning to fill the tube with ink. Confirm by
turning OFF the printer and open the Front Cover. If not enough or the "empty" air is large, execute Initial
Cleaning in [ Maintenance ] menu. to replace the old ink.
<Note>
As for White Ink, you do not have to load Maintenance Solution, go on the Initial Cleaning with White Ink Cartridge
with "Maintenance Cartridge" is indicated on the Display, and press the Stop Button to discontinue the operation
after 10 seconds.
If the problem is not solved, proceed to the next step.
