Pentax PocketJet 3 - Manual (Page 56)

Data Receive Error
Data is being received but errors are causing the printer to request that it be
re-transmitted. This will slow printing speed and is almost always
associated with the quality of an IrDA connection. Try repositioning the
printer or host IrDA until the errors cease.
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
the sample in the Set-Up Utility section) 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 Installation Disk.
