D. TROUBLE SHOOTING
This section gives solutions to some printer problems you
may have.
1. General Problems
No LED lights up on control panel when switched on –
Make sure that the power supply cables are correctly plugged into
the printer, the power adaptor and to the power outlet. Make sure
that power is supplied to the power outlet. If the outlet is
controlled by a switch or timer, try use another outlet.
2. Printing Problems
Nothing can be printed with ERROR LED ON – Check
the Paper Out LED. If it is ON, most probably the paper roll is not
installed or is at or near the end. Install a new paper roll. If the
Paper Out LED is OFF, please check if the top hood is properly
closed. There are 2 internal check points inside the printer to
assure the locking of the hood for a decent printing. Therefore any
dislocation of the hood may cause an error status and inhibition to
printing. Press down the hood at middle of the opening when
closing it till it audibly clicks into place. If both situations are not
the cause, please try pressing the hood lock button down again. If
the top hood won’t release automatically, check for paper jam
described in next item.
If there is no paper jam and the printer has been printing for
quite a period of time, the print head may be overheated. It will
usually cool back in few minutes and the printing will resume.
