Part 1: Safety and Precautions
1.3 BJ Cartridge Heat-Up
Do not touch the BJ cartridge's aluminum plate. The aluminum plate heats up during
printing and becomes particularly hot during prolonged and continuous printing. It can
overheat also if printing is continued even after the cartridge has run out of ink.
NOTE
REF.
Aluminum Plate
Caution! High Temperature!
Figure 1-5 BJ Cartridge Aluminum Plate
The printer has a protective mechanism when the BJ cartridge heats up.
The protective mechanism is activated when the head temperature (diode)
sensor in the BJ cartridge senses a certain temperature.
Protection level 1:
This level prevents the user from touching the bubble jet head's hot
aluminum plate when the bubble jet head is replaced. For this
purpose, when the front cover is opened, the carriage will not move to
the cartridge replacement position. Close the front cover, leave the
printer inactive for a few minutes to allow it to cool, and then open the
front cover again to perform the required operation.
Protection level 2:
If a high temperature is still detected, the carriage is returned to the
home position for 3.5 seconds to bring down the temperature. After the
resting period, printing will resume. This continues for over 20 seconds
to lower the bubble jet head's temperature.
Protection level 3:
If the temperature continues to increase, a head temperature error
occurs. This stops the printing operation.
When printing is stopped by a head temperature error or a head
temperature sensor error, follow the troubleshooting procedures in
5.TROUBLESHOOTING (page 5-6).
