Intermec EasyCoder PF4i Service Manual

Intermec EasyCoder PF2i, PF4i, and PF4i Compact Industrial—Service Manual 231
Chapter 15—Troubleshooting
Description:
Media feed does not work properly.
Possible Causes and Suggested Remedies:
• Faulty stepper motor.
- Connect a replacement stepper motor to P10 on the Power Supply
Unit (see Chapter 12) and perform a PRINTFEED or FORMFEED
operation. If this motor runs, the original stepper motor is probably
damaged and needs to be replaced (see Chapter 7.3).
• Dirty or worn platen roller.
- Inspect the platen roller for visible wear. Replace if necessary (see
Chapter 7.2).
- Clean the platen roller using a cleaning card or a soft cloth moistened
with isopropyl alcohol. Paper dust or adhesive residue can deteriorate
the media feed function or make the media slip.
• Intermec Fingerprint instruction missing.
- Verify that a print command is actually issued in the current Intermec
Fingerprint program.
• Power Supply Unit malfunction or bad connection.
- The stepper motor could be incorrectly connected to P10 on the
PSU, or its drive circuit (U13) on the PSU could be damaged.
- Check that all pins in the connector of the stepper motor’s cable are
fully inserted.
- Measure the +24VDC on the CPU board, see Chapter 13.4. If there
is no power, when an attempt to print is made, the power supply unit
is probably faulty.
Description:
Partially compressed print image.
Possible Causes and Suggested Remedies:
• Jerks in the media feed caused by for example a large media supply roll
in combination with a high print speed setting.
- Refer to the User’s Guide (Setting Up the Printer/Print Defi nes/Print
Speed) for restrictions of print speed in combination with certain sizes
of media supply.
Description:
Excessive wear of printhead.
Possible Causes and Suggested Remedies:
• Various reasons.
- Refer to Chapter 7.6 “Printhead/Precautions” for advices on how to
reduce the wear of the printhead.
