information.
• Verify approximately 55 ohms in the
solenoid. If not correct, replace the solenoid.
• Verify the solenoid has the spring in place
and functions mechanically. If this is true
and the resistance is correct, replace the
controller card assembly.
Note: Always check printhead alignment
after replacing the controller card assembly.
See "Printhead assembly adjustment" on
page 4-2 for hardware alignment of the
printhead.
Action
Check the paper feed roll (D–roll or pick roll) for
wear. Verify that the extension spring is
working properly. Replace as necessary.
During a paper pick, the paper feed assembly
is released by the solenoid. Verify the plastic
end of the shaft is not worn allowing the shaft
to be released without the solenoid being
activated. Replace the paper feed assembly as
necessary.
Note: We recommend that the paper feed roll
be replaced when the paper feed assembly is
replaced.
