Printer Error Conditions
Error
Description
Corrective Action Required
Paper Out
Printer does not detect paper.
Load paper correctly.
Print Head
Printer senses an internal error
due to connectivity or an interface
problem with the Thermal Print
Head. This condition may occur
due to a cabling problem between
the Main Controller Board and the
Printer Engine.
The Printer will remain in this condition until the power is cycled or the Unit
is reset. If the problem persists, the Printer may require service. Contact JCM
Customer Service for assistance.
Temperature
Printer is operating outside of
allowable temperature range
specifications. If the operating
environment ambient temperature
is equivalent to room temperature,
the error may be due to a hardware
problem.
The Printer will automatically resume operation after the detected Head
Temperature falls within allowable temperature range specifications.
Voltage
Printer detects a Power Supply
Voltage outside of allowable range
specifications. The error could be
due to improper cable connection.
The Printer will automatically resume operation after the Power Supply
Voltage is detected to be within range specifications (+21VDC to +25VDC).
Missing Black
Index Mark
The Selected Paper Type is
Indexed Paper, but the black Index
Mark is not detected within
approximately 10” of paper feeding
or printing.
The error may occur due to the
paper being loaded in the wrong
direction (so that the black Index
Mark is rotated 180°) or due to an
incorrect paper type being loaded
into the printer.
Check the paper supply and orientation.
Paper Jam
Printer detects an error in the
Paper Path for Presenting the
Ticket.
Open the Printer Head and inspect the Paper Path for a jammed Ticket.
