If there is no paper jam and the print head is not overheated,
turn off the printer and wait for half a minute then turn it back on.
If the problem still remains, contact a qualified service person.
Nothing can be printed with ERROR LED OFF
– Try to
run self-test according to previous chapter to check if the printer
itself works properly. If the self-test passes, check the following:
a. Check the connection of the interface cable at both the
printer and computer ends. Also make sure that this cable
meets the specification required for both the printer and
the computer.
b. Check the printer data communication settings against the
computer. The printer settings can be found easily on the
self-test print out.
If the problem remains or the self-test fails, contact your
dealer or a qualified service person.
Poor printing quality
– Contaminants like paper scraps and
dusts on the thermal print head can lower the print quality
drastically. Clean the print head as described in previous section.
Printer trembles when printing
– Since PP-5000/PP-5200
prints at 120 or 220 mm / sec that is extremely high speed, the
printer may tremble due to frequent engagement of the brake and
acceleration of the motor. Such situation in turn can be
consequences of very complicated printer operation command or
heavily dense printing (like in inverse printing) in print content or
irregular / insufficient data flow received from the host. When this
happens, the print speed will be dragged down drastically since
the motor has to be stopped frequently. Avoiding such drawbacks
can free the printer from trembling and degraded performance.
However, if it is impossible to avoid this for the serial interface
printer, increasing the baud rate to 38400 bps in the host system
