Self-Test Feature - Pentax 3 User Manual

continues to fail in the same way, it is likely that the file itself is
corrupt and should be replaced with a clean copy of the file.
In rare cases, when the printer is not being flashed, this error may
indicate bad memory components or other problems that require
printer service.

Self-Test Feature

The Self-Test Feature can be used to print a letter-size page test
page without connection to a host computer. The test page (see
page 34) contains firmware level, image quality, and
configuration information.
1. To print a test page, the printer must be turned on and idle,
and paper must not be loaded in the printer.
2. Press the main switch for two seconds and release to place the
printer in "Service Mode". The red DATA light will
illuminate.
3. Insert a piece of Pentax Quality paper in the printer. The test
page will print automatically. After the print is complete, the
printer will return to an idle state.
4. To print multiple pages, repeat steps 1~3.
Note: Test pages can also be printed from the Windows based
Configuration Utility provided on the CD.
