This utility can assign to each LAN printer a different device name for easy recognition. In case of confusion, please check the MAC addresses listed in this utility against the MAC address label you can find under each printer. Printer Driver Setup Any PC connected in same network can use TCP/IP to use PP-8000L in the way like a directly connected local printer. So, for direct I/O control by tools like “HyperTerminal” all commands applicable to the serial or parallel interface model can work on PP-8000L in the same way as PP-8000 except the port must be TCP/IP with the IP address of the printer. Similarly, for Windows printer driver setup, please “Add Printer” and select for “Local printer” and select port “TCP/IP” with the printer IP address then use the same Windows printer driver of PP-8000 for PP-8000L. Part 10 OPERATION GUIDE MAINTENANCE GUIDE LINES .. Always turn off and disconnect power before opening the cover. .. The areas around the print head and motor become very hot during and just after printing, DO NOT touch them. .. When handling the interior of the thermal printer, please pay attention not to be hurt by any sharp edge of the metal parts. GENERAL CLEANING Please use soft hairbrush or compressed air to clear away any dust or paper scraps accumulation inside the printer. Check also the area of the auto- cutter regularly. PRINT HEAD CLEANING The print head is located underneath the roll paper passage at the exit as in the picture below. You can clean the thermal elements of the print head and paper sensor gently using a cotton swab moistened with isopropyl alcohol solvent. NOTE: Never do this when print head is still hot Do not touch the print head thermal elements Do not scratch the print head Thermal Elements Paper Sensor Before putting back the paper roll for printing, alcohol solvent must be dried completely. TROUBLE SHOOTING This section gives solutions to some printer problems you may have. 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 Part 11 Printing Problems Nothing can be printed with ERROR LED flashing – Most possible cause for the flashing Error LED is that the printer has been printing for quite a period of time and the print head temperature become too high. After few minutes under normal ventilation, the print head should be able to cool down and the Error LED will stop flashing. Printing will resume after cooled down. If this is not the case, contact a qualified service person. Nothing can be printed with ERROR LED ON – Check the Paper Out LED. If it is ON, most probably either the paper roll is not installed or the paper roll is at or near the end. Install a new paper roll. If the Paper Out LED is OFF, please check if the print 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 pulling the hood lock forward. If the top hood won’t release automatically, check for paper jam described in next item. 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: 1). 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. 2). 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. Paper Jam Problems Paper is jammed inside the printer – Turn off the printer and open the top hood by releasing the hood lock. Remove the jammed paper and reinstall the paper roll. Close the hood properly and firmly. Then turn on the printer for operation. If the auto cutter is jammed, the top hood will be locked. Please first Part 12 Part 13 resolve the auto cutter problems per description in next item and then come back to deal with the paper jam. Never force open the top hood. Please also clear away any contaminants ...
