RECEIPT PRINTER PROBLEMS
Series 1000 does not print any receipts and may not prompt for receipts.
Possible Cause Checks Corrective Action
The Printer Status PCB power
switch is off. Verify that the Printer Status
PCB power switch is on. Turn switch on, if off.
The receipt printer is not in
online mode Check the online LED on the
Printer Status PCB to see if it
is lit. Press the online button on the
Printer Status PCB to place
the printer online.
Poor connection or wrong
baud rate selection. Examine the baud rate jumper
for port 2 on the Auxiliary
Communications Port PCB.
Verify correct rate (9600) and
good electrical connection. Choose correct rate (9600)
and make good electrical
connection.
Problem in RS-232
communication between
Series 1000 and receipt
printer. Turn off the power switch on
the Printer Status PCB. While
holding the paper feed switch
in, turn the power switch on.
This will generate an internal
self-test and the printer should
begin printing. If the printer performs the
internal self-test, replace the
Auxiliary Communications Port
PCB. Replace the Star
Controller PCB if replacing the
Auxiliary Communications Port
PCB did not correct the
problem.
If the printer did not perform
the internal self-test, replace
the Star Controller PCB.
Replace the Star Printer
mechanism, if replacing the
Star Controller PCB did not
correct the problem.
Receipts are printed but cutter bar does not cut receipts.
Possible Cause Checks Corrective Action
No drive signal from Star
Controller PCB or defective
cutter mechanism. Using a DC voltmeter,
measure between CN3, pin 2
(drive signal) and CN3, pin 3
(ground) of the Star Controller
PCB. A 12VDC level should
be measured until the cutter
bar is to be activated. The
level drops to 0VDC and
returns to +12VDC. Replace the Star Controller
PCB if no change in voltage
level is measured.
Replace the printer
mechanism if the voltage level
changes but the cutter is not
activated.
