Maintenance Overview 162
Confidential6.1  OverviewThis section provides information to maintain the printer in its optimum condition.6.1.1  CleaningThis printer has no mechanical components which require regular cleaning. Therefore, 
when returning the printer to the user, check the following parts and perform 
appropriate cleaning if stain is noticeable.
Housing
Use a clean soft cloth moistened with water and wipe off any dirt. If the Housings 
are stained with ink, use a cloth moistened with neutral detergent to wipe it off.
Inside the printer
Use a vacuum cleaner to remove any paper dust.
6.1.2  Service MaintenanceIf print irregularity (missing dot, white line, etc.) has occurred or the printer indicates 
“Maintenance Error”, take the following actions to clear the error.6.1.2.1  Head CleaningThe printer has a built-in head cleaning function, which is activated by operating the 
control panel.The procedure is given below.
1. Confirm that the printer is in stand-by state.
Check that the Power LED is not flashing.
2. Hold down the Ink Switch on the control panel for more than 3 seconds.
The Power LED flashes during the cleaning sequence.

Never use chemical solvents, such as thinner, benzine, and 
acetone, to clean the exterior parts of the printer like the 
housing. These chemicals may degrade or deteriorate the 
quality of this product.
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 dust.
Use a soft cloth moistened with dilute alcohol to remove ink 
stain.
Do not use the supplied cleaning sheet for normal usage. It may 
damage the coated surface of the PF Roller. If the adhesive 
surface of the cleaning sheet is set to the ASF LD Roller side 
and used to clean the ASF LD Roller surface, it is no problem.
When using compressed air products; such as air duster, for 
cleaning during repair and maintenance, the use of such 
products containing flammable gas is prohibited.



For Head Cleaning, it is recommended to run the nozzle check and 
the cleaning alternately to minimize ink consumption.

Maintenance Overview 163
Confidential6.1.2.2  Maintenance RequestWaste ink is discharged to Waste Ink Pads via the Cap Unit. The printer has counter 
function that counts how much waste ink is held in the Waste Ink Pads and stores the 
value in the EEPROM as Protection Counter A  and Protection Counter B (home 
and non-home side). When the counter reaches the predetermined upper limit, the 
printer causes the Maintenance Request error to indicate that the Waste Ink Pads is 
nearly saturated.
Protection Counters Upper Limit
Timing for Replacing the Waste Ink Pads
When the Protection Counter reaches the value shown above, a Maintenance 
Request is indicated.
When servicing the printer, always check the Protection Counter using the 
Adjustment Program regardless of whether the Maintenance Request error has 
been indicated or not. If the counter is close to its upper limit shown above, 
replace the Waste Ink Pads and reset the counter to 0 with receiving prior 
approval from the user. This prevents the printer from causing the 
Maintenance Request error soon after it is returned to the user.Waste Ink Pads to be replaced
After the Replacement
Reset the Protection Counter (Refer to Chapter 5 Adjustment (p.137))
