The self test is suspended if the printer is out of paper, or, in the
Model 2225B, the battery voltage is too low to run the motors. When either of
these conditions is fixed the self test will resume.
The self-test-failed bit in the printer status byte is set only when the
non-printing portion of the self test fails.
(If the test failed because the
carriage position cannot be determined, the carriage motion disabled bit is
If the test is suspended because the printer is out of paper, the out of
paper bit is set.
If the test is suspended because the battery voltage is too,
low, the low battery bit is set.)
There are three different methods for returning your printer to its preset
(default) print features. These are as follows:
Simply turn the printer off and then on. All print features
return to their default setting and top of form is set to the current
Enter the escape sequence:
This causes the printer to print whatever data is in the print
buffer, set all changeable features to their default settings, and,
if the paper is not at the top of form, execute a form feed.
Send a device clear frame (DCF) to the printer. This reset causes
the printer to stop printing (immediately), clear all remaining data
in the print buffer, set all changeable features to their default
setting, and execute a form feed if the paper is not at the top of
In addition if the print head carriage jams or is moved manually while the
printer is on, the printer will stop printing. In this event, the print
buffer is emptied, all print features return to their default settings, and
the attention light begins blinking.
Maintenance of the Printer Battery Pack and Recharger.
Under normal operating conditions, a fully charged battery pack is capable of
Continuous printing without using the recharger: over one and a half
hours, or approximately 200 pages
several weeks without recharging
Not printing with power left on: five days
To maximize battery pack life, recharge the battery pack only when it is
nearly discharged, as indicated by the printer power light. Approximately
eleven hours is required to recharge a battery pack fully. The battery pack
may be charged in or out of the printer.
