3.1.4.6 Remedy when an adjust lever error occurs
This section describes the check points to be carried out in order to remedy errors that
occur when the printer mechanism's paper guide is open.
The various causes of this error and how to remedy them are given below. You should
carry out the checks in the order specified. As a guide to understanding the table, if the
answer to the question for a check item is yes, then carry out the operation given next
to that question. If the answer is no, proceed to the next step.
11 Is there a
malfunction of
the CR motor
encoder (photo
sensor)? Replace the junction board on the underside of the carriage that
the encoder is mounted on, and check operation.
NOTE: Once the carriage or the carriage guide shaft have been
removed, several adjustments must be carried out, so
refer to the "Adjustment" and "Disassembly" sections
for details on carrying out these adjustments correctly.
Table 3-10. Countermeasures when a fatal error occurs
Step Check Point Remedy
Table 3-11. Countermeasures when an adjust lever error occurs
Step Check Point Remedy
1 Is the Adjust
lever set
correctly? If the Adjust lever is set to the back position, move it to the
forward position.
2 Is connector
CN13 (yellow:
3-pin) on the
main circuit
board or the
sensor connector
disconnected or
loose? Connector CN13 on the main circuit board is used to send the
feedback signals from the adjust lever to the main circuit board.
Therefore, if this connector is disconnected, the same operation
occurs as if there is a problem with the Release sensor itself.
