Before putting back the paper roll for printing, alcohol solvent must be dried completely.
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.
