ADJUSTMENT
This section describes the adjustment procedures required when reassembling the printer. If
disassembly or replacement is performed during maintenance or repairs, be sure to perform the
following adjustments. Although each section explains when these adjustments are required, they can
also be performed when the printer doesn't work as usual or when print quality is not good.
DANGER
Perform the adjustment with the power source disconnected, unless otherwise mentioned.
4.3.1 Trigger Solenoid Adjustment
This adjustment is performed when assembling the trigger solenoid. Be sure to perform this adjustment
priorto attaching the other parts such as the carriage motor. This adjustment is required in the following
case.
•
When the trigger solenoid or trigger lever is removed.
This adjusts the clearance at the point where the trigger solenoid lever meets the release planetary
gear set. (Clearance should not be too narrow nor too wide.) If this adjustment is not performed correctly,
the following may result.
•
Paper selection (selection of tractor or friction feed) won't be performed correctly.
•
Paper feed motor will continue to rotate during paper selection.
Step 1 Fix the paper feed knob and rotate the platen (5 or 6 times) by pulling the trigger lever with
your finger. (Paper select will switch.)
Step 2 Remove your finger from the trigger solenoid and remove the paper feed knob.
