EPSON Stylus COLOR C70/C80
Revision A
Troubleshooting
Overview
62
3.1.1 Communication Error
This section describes the procedures for solving the problem when no communication
at all is received from the computer after the printer power has been turned on, even
when initialization has completed normally and the printer is at the standby condition.
3.1.2 Too Late Throughput
This section describes the procedures for checking printers that have been returned
because the printing speed suddenly became much slower after having operated
normally up until then. Basically this problem is unlikely to occur in Windows and
Macintosh environments because the printer driver is used to transmit data and
commands, but it is possible that customers using the printer in a DOS environment
may experience this problem.
NOTE:
If the problem does not disappear or if it cannot be reproduced when
these checks are carried out, refer to "CR Motor Operation Abnormal" in
Section 3.1.6.11.
Table 3-1. Communication Error Checking Point
Step
Check Point
Remedy
1
Is the customer's
I/F cable broken?
If communication is possible at all times while working, proceed
to the next step. If communication is not possible, change the
interface from parallel to USB or vice versa and check if
communication is then possible. If there is still no
communication, continue to the next step.
2
Use the
adjustment
program to check
the 60H address
(interface
protocol setting)
for the EEPROM.
The relationship between the interface protocol setting status and
the setting values is given below.
00H: Auto (Default value; communication problems should
never occur with this setting.)
01H: Fixed to Parallel (Communication problems occur when
using USB)
02H: Fixed to USB (Communication problems occur when
using parallel)
To reset, use the Dump function of the adjustment software to
rewrite the setting to the default (00H). The relationship between
the interface protocol setting status and the setting values is given
below. For details, refer to Chapter 5.
NOTE:
The Stylus COLOR C80 has a default setting function, but
unlike previous models, interface protocol selection is not
possible. Furthermore, the Stylus COLOR C70 does not
have its own default setting function. Even if the default
value (00H) is changed to 01H or 02H, the EEPROM
data may become corrupted, so even if the
communication problem is fixed, there is a high
possibility that the various adjustment values may be
distorted. Because of this, all parameter electrical
adjustments should be carried out afresh. Refer to
Chapter 5 for details.

EPSON USB Port
(Only for USB
User)
If no problems occur when the above two checks are carried out,
check with the customer whether the USB port has been installed
correctly or not, and if necessary get the customer to reinstall the
driver and re-check. (However, this is only for customers who are
using USB.)
Table 3-2. Too Late Throughput
Step
Check Point
Remedy
1
Use the adjustment
program to check the
50H address for the
EEPROM.
The relationship between the setting status and the
setting values is given below.
00H: Bi-D
01H: Uni-D
02H: Auto
To reset, use the Dump function of the adjustment
software to rewrite the setting to the default (02H).
The relationship between the interface protocol
setting status and the setting values is given below.
00H: Auto (Default value; communication
problems should never occur with this
setting.)
01H: Fixed to Parallel (Communication problems
occur when using USB)
02H: Fixed to USB (Communication problems
occur when using parallel)
To reset, use the Dump function of the adjustment
software to rewrite the setting to the default (00H).
Refer to Chapter 5 for details.
NOTE:
The Stylus COLOR C80 has a default setting
function, and it can be used for setting this
item also, so that the setting can be returned
to the default without using the adjustment
software.
