3. Light the printers inside through a gap between the Roll Paper Frame and the ASF 
Assy with a penlight, and look the tab on the Retard Roller Holder at the back of 
the two reference tabs on the ASF Assy through the notch. After making sure that 
the two reference tabs are aligned when viewed edge-on, adjust the position of the 
Retard Roller Holder Tab by pressing the Guide Roller LD (0 digit side) so that it 
is placed within the range as shown in the simplified diagram in Figure 5-28.
Figure 5-28.

4. Align the guide pin and tab on the 0 Digit Side Guide Roller LD with the 
positioning holes on the Main Frame, and tighten the Guide Roller LD (0 Digit 
Side) with the screws. (See Fig.5-29.)
5. Check the position of the Retard Roller Holder Tab again through the notch. If it is 
not inside the range, remove the screws on the Guide Roller LD (0 Digit Side), and 
repeat steps 2 to 4 to set the tab within the range.
6. Check the clearance in both ends of the positioning hole that the Guide Roller LD 
Tab is inserted. And align Guide Roller LD (130 Digit Side) to the same height, 
and tighten with the screws.

6.1  Overview
This section provides information to maintain the printer in its optimum condition.
6.1.1  Cleaning
This 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 Maintenance
If 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 Cleaning
The 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.

6.1.2.2  Maintenance Request
When the ink is used for the Print Head cleaning and such, it is drained via the Cap 
Unit to the Waste Ink Tray Assy located on the Lower Housing. As for the ink 
absorbed by the Front Paper Guide Pad when carrying out the borderless printing or 
flushing operations, it is drained to the ink pads in the Front Paper Guide Pad Tray. The 
amount of the waste ink is controlled with the Protection Counter A (Waste Ink Tray 
Assy) and B (Front Paper Guide Pad Tray) in the EEPROM on the Main Board. When 
the amount reaches the specified value; which indicates that the waste ink has reached 
the limit of the absorbing capability of the Waste Ink Pads, the “maintenance request 
error” is displayed.
Protection Counters Upper Limit
Note* : Taking the ink evaporation amount into consideration, the threshold 
value of the Protection Counter A for the Maintenance Request varies 
from 12,300 to 14,250 accordingly until 260 days pass from the day the 
printer receives the first TI from the printer driver (the printer is initially 
used). The value after 260 days is 14,250.
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
