Note: Paper head signals shall be converted by means of 8-bit A/D conversion.

 PW Detector Control

There are two controlling methods using PW detector as follows:

 Control of preventing print with no characters

Before start of print (immediately after paper head feed is complete) or during print, this control detects the existence of paper with PW detector, driving CR and PF motors and prevents print with no characters on paper sent to paper guide, which applies to only right and left edges of paper.

 Control of restriction to run-off

This control detect paper edges with PW detector at the time of printing with no margin, and restrict the printing run-off quantity. It detects 4 edges when no margins are set for 4 sides of paper. For each mode, run-off area thin-out control is set that further compensates for run-off mask area at the time of printing with no characters.

Photoelectric conversion method (reflection type) (SHARP GP2S40V)

Collector withstand-voltage: not more than 30V Sinc current : not more than 0.2mA Driving voltage : 3.3 ± 5%

MAINTENANCE

CHAPTER

EPSON Stylus PHOTO RX600/610, RX620/630 Revision C

6.1 Overview

This section describes maintenance work to maintain the functions and performance of this product.

6.1.1 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.

 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.

 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.

 Waste ink pad counter count up ≥ 20000 ~ 46750  Time for replacing the Waste Ink Pad

When the total amount of waste ink reaches the predetermined limit, the printer indicates “Maintenance Request”. 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.

 Treatment after replacement

Reset the Waste ink pad counter. Turn on the power to the printer and enter into the special menu (ordinary operation) and execute waste ink counter reset menu or perform counter clear by the adjustment program.

6.2 Cleaning

Clean if dirt is visible. As dirt on the glass for placing the document affects directly image reading quality, clean the glass completely.

C A U T I O N

 Exterior parts

Use a clean soft cloth moistened with water and wipe off any dirt. If the exterior parts are very dirty, use a cloth moistened with a neutral detergent to wipe it off.

 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.

 Never use chemical solvents, such as thinner or benzine, as they

may deform or deteriorate plastic and rubber products.

 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.
