Be careful not to damage any components when you clean
inside the printer.
Do not scratch the surface of the PF roller assembly. Use a soft
brush to wipe off any dust. Use a soft cloth moistened with
alcohol to remove ink stain.
Do not use frequently the cleaning sheet included in the media.
It may damage the coated surface of the PF roller.
However, it is no problem to clean the surface of the ASF LD
roller by placing the adhesive surface of the cleaning sheet on
the ASF LD roller.
6.1.2 Maintenance of the Scanner
6.1.2.1 Lubrication Points of the Scanner (TBD)
When any part of the CR Unit of the scanner has been replaced or the sound of carriage
moving is loud, lubrication is necessary. Figure 6-1 and Figure 6-2 below indicate the
designated grease and lubrication points.

If lubrication exceeds the designated volume, the mechanism may be
damaged or functions may be impaired. Be sure to apply the
designated volume of grease correctly.

Inside the printer
Use a vacuum cleaner to remove any paper dust.
Glass for placing the original document on
Remove dust or any paper with a clean dry cloth. If dirt is serious or foreign
material is adhering, wipe it off with a cloth moistened with a neutral detergent. If
a trace of wiping has remained, wipe the glass again with a dry clean cloth.
ASF LD Roller
If paper dust on the surface of the ASF LD Roller lowers the friction, place the
adhesive surface of the cleaning sheet included in the media on the surface of the
ASF roller and repeat paper loading from the ASF.

6.1.3 Maintenance of the Printer
If print irregularity (dot missing, white line, etc.) has occurred or the printer indicates
“Maintenance Error”, take the following actions to clear the error.
6.1.3.1 Head Cleaning
The printer has a built-in head cleaning function, which is activated on the operation
panel. Confirm that the printer is in the stand-by state (the power indicator is not
blinking). Select “Head Cleaning” by means of the Menu buttons on the operation
panel and execute it, and the printer will start head cleaning.
6.1.3.2 Maintenance Error
Ink is used not only for printing but also for other operations, such as cleaning. During
such an operation, the printer wastes a certain amount of ink and drains it into the waste
ink pad, and the amount of the waste ink is counted.
Once the amount of waste ink reaches the predetermined limit, the printer indicates
“Maintenance Request” and the waste ink pad must be replaced.
Overflow Counter (Protection Counter) count up ≥ 23270
Time for replacing the Waste Ink Pad
When the total amount of waste ink reaches the predetermined limit, the printer
indicates “Maintenance Request”. (Refer to “TBD”). During repair operation,
check the overflow counter and the firmware version, selected code page and
nozzle check pattern.
If the ink counter value is close to its upper limit, notify your customer and
recommend that the waste ink pad is to be replaced. (If the waste ink pad is not
replaced at that time, “Maintenance Error” will occur just after the printer is
retuned to the customer.) Once you have the confirmation from the customer,
replace the waste ink pad.
6.1.3.3 Lubrication Points of the Printer
The kinds and volume of the oils and grease for lubrication of the Printer are
determined based on factory evaluation. Therefore, be sure to apply a specified volume
of the designated grease to each designated point for repair and maintenance of the
Printer. The designated grease and application points are indicated below.
C A U T I O N
KindNameParts CodeAvailable from
GreaseG-461039172EPSON
GreaseG-581082176EPSON
Never use any oil or grease other than designated, since any
other oil or grease can badly affect the machine life or function
of the product or damage the mechanism.
As the volume of application is also designat ed ba sed o n
evaluation result, be sure to apply the designated volume of
grease correctly.
