			When “Fit to Page” is selected by the key operation, a copy is made
			adjusting the image size to the paper by enlarging/reducing the
			original. The zoom ratio is determined as follows, and the same ratio is
			applied to both horizontal and vertical sides.
			• Detects the image size of the original using the preview function.
	Fit to Page		• Calculates an appropriate zoom ratio from the image size and the
			printable area of the paper.
			• If the ratio falls into less than 25%, 25% is applied. 400% is applied
			if over 400% likewise.
			• For color/B&W copying, the zoom ratio is determined so as to
			make a copy of the whole image of the original on the paper.
			• For photo copying, the zoom ratio is determined so as not to leave
			any margins on the paper.

1.7.4 Multiple Copying

Making 20 (fixed value) copies in color/B&W becomes available by operating specific keys (Refer to p.18). In this copying, the second copy or later are carried out without scanning by storing the scanned data in the memory to makes copying faster. However, if the scanned data is bigger than the memory’s capacity, scanning will be repeated for each copy. The conditions that the scanned data can be stored in the memory are as follows.

3.1 Overview

This chapter describes how to solve problems.

WARNING

Be careful to avoid electric shocks when checking the electrical circuit boards (MAIN and PSE/PSB boards) while the power is turned on.

Touching an FET, transistor or heat sink with one hand while touching a metal part of the mechanism with the other hand could result in an electric shock, so carefully avoid this.

After initial filling of ink has been repeated several times, immediate moving or tilting of the printer could result in leaking of ink that has not been completely absorbed by the Waste Ink Pad. When initial filling of ink has been repeated several times, check the ink remaining in the tip of the Waste Ink Tube and the waste ink not absorbed by the Waste Ink Pad before moving the printer.

CHECK	Disassembly and reassembly of parts is often required when
POINT	identifying the causes of problems. The parts should be
	disassembled and re-assembled correctly while referring to
	“DISASSEMBLY/ASSEMBLY” (p.54) so that the operation
	and status of each check item can be correctly verified.

Some individual part and units may require adjustment once they are removed or replaced. If removing or replacing parts which have specific instructions for adjustment included in “DISASSEMBLY/ASSEMBLY” (p.54), be sure to make these adjustments after repairing the problem location.

3.1.1Specified Tools

This printer does not require any specified tools for troubleshooting.

3.1.2 Preliminary Checks

Before starting troubleshooting, be sure to verify that the following conditions are all met:

The power supply voltage must be within the specification limits. (Measure the voltage at the wall socket.)

The power code must be free from damage, short circuit or breakage, or miswiring in the power code.

The printer must be grounded properly.

The printer should not be located in a place where it can be exposed to too high or low temperature, too high or low humidity, or abrupt temperature change.

The printer should not be located near waterworks, near humidifiers, near heaters or near flames, in a dusty atmosphere or in a place where the printer can be exposed to blast from an air conditioner.

The printer should not be located in a place where volatile or inflammable gases are produced.

The printer should not be located in a place where it can be exposed to direct rays of the sun.

The printer must be placed on a strong and steady level table (without an inclination larger than five degrees).

Any vibrating equipment must not be placed on or under the printer.

The paper used must conform to the specification.

There is no error in handling of the printer.

Check the inside of the printer, and remove foreign matters if any, such as paper clips, staples, bits of paper, paper dust or toner.

Clean the inside of the printer and the rubber rolls.

3.2 Error Indications and Fault Occurrence Causes

This chapter describes how the printer indicates an error status with LEDs, and why the error is caused, when a problem happened during each sequence/operation (power-on sequence, paper feeding, ink drawing, and so on).

Table 3-1. Error Indications and Fault Occurrence Causes

Error Name		LED Indications				Error Cause	Reference
		Power	Paper		Ink
Fatal error (scanner)		High-speed	High-speed		High-speed	• RAM trouble occurs.
		flashing	flashing		flashing	• System trouble occurs.	Table 3-2. (p30)
Fatal error (printer mechanism)		Flashing	Flashing		Flashing	Mechanical trouble occurs.(CR error, PF error etc.)
Maintenance error (waste ink overflow)		Flashing	ON		ON	The waste ink counter exceeds to capacity.	Table 3-3. (p36)
Paper jam error		--	Flashing		OFF	Paper stays in the paper path after paper ejection.	Table 3-4. (p37)
Paper out error		--	ON		OFF	Failure to load paper to print.	Table 3-5. (p40)
Double feed error		--	Flashing		OFF	Double feed during double sided printing.	Table 3-6. (p42)
						• The cartridge has run out of ink.
Ink out error / No ink cartridge error/		--	OFF		ON	• The printer could not detect the cartridge.	Table 3-7. (p43)
Ink cartridge detection error						• The printer detected non-Epson cartridge.
						• Writing to/reading from the CSIC could not be made.
Note : --:	No change
Flashing:	Repeats ON and OFF every 1.25 seconds.
High-speed flashing: Repeats ON and OFF every 0.5 second.

3.2.1 Troubleshooting by Error Message

The following tables provide troubleshooting procedures. Confirm the error message indicated on the LED or the STM3 screen on the PC’s display, and verify it in the following list and the figures at the end of this chapter for the corresponding troubleshooting remedy. If some parts need to be replaced or repaired, make sure to follow the procedure given in Chapter 4 “Disassembly / Assembly”.
