Diagnostic Aids

Call Monitoring

Call Monitoring plays tones during the call connection. This is helpful
in diagnosing communication problems.
To invoke this aid, press Setup, then select SPK. Press an arrow key
to turn the speaker on or off, press OK to save the setting and then
press Stop.

Error Report

When a fax transmission cannot be completed, the machine prints
an Error Report. This is useful in determining whether service is
required to correct the communication problem.

Frame Service Position

For ease of access to the electronic boards, the frame can be piv-
oted out of the way without being removed. Remove the covers. Dis-
connect the cables from the frame on the right side of the printer and
fax boards. Unsnap the right front and right rear frame supports from
the machine base. Pivot the printer frame up 90 ° on the left feet.

Hex Print Mode

Perform this test with a black print cartridge installed. Use hex mode
to help evaluate data stream problems. All data (including both con-
trol and character data) print in hexadecimal digits instead of ASCII.
To activate, press Setup, then select PRT. Use the right arrow to
move the cursor to Diag and press OK. Select HEX. Then send the
PC job to be printed in hexadecimal.
Press Stop to return to ASCII mode, and press Stop again to exit
from the service menus.
