When Something Goes Wrong

Other Serious Problems
The following problems all need to be corrected by a qualified service
representative. For more information on contacting a representative, see the
next section.
• Printer does not cycle or stop when required.
• Illegible characters or light print.
• Paper does not feed.
• Platen does not open or close.
• Printer does not communicate
• MICR check reader not reading characters on checks
Note: The MICR check reader feature has been factory adjusted for a
normal operating environment with a host computer. However,
additional devices, such as CRT monitors or large metal surfaces
near the printer, can affect the printer’s magnetic field, causing
intermittent reading errors when the MICR check reader is in
operation.
This condition can be easily diagnosed by checking the noise level of the MICR
check reader. See “Checking MICR Noise Level” in section 3 for more
information.
Getting Service
For serious problems, such as the printer not printing or not communicating
with the host computer, contact a Unisys-authorized service representative to
arrange a service call.
