JP 500 (260-2950) Installation Faxback Doc. # 3636 This chapter describes how to connect the AC/DC adapter to the printer, how to load batteries or a battery pack, how to insert the ink jet print head in the printer and how to insert the ink jet print head in the printer and how to connect the printer to a host computer/system. Connection to the AC/DC Adapter Place both the printer and the AC/DC adapter on a flat, stable surface. Make sure the AC/DC adapter is NOT plugged into the AC wall socket and that the printer is switched OFF. Plug the AC/DC coaxial cable connector into the socket marked DC-IN on the right hand side of the printer. Connection to the Mains Power Supply (AC wall socket) ! BEFORE connecting the AC/DC adapter to the mains supply and/or switching on printer, read all the following points carefully. The manufacturer declines all responsibility for accidents to persons or damage to the printer arising from the non-observance of the following procedure. Make sure the mains power supplies the voltage indicated on the electrical data plate on the base of the AC/DC adapter. ! If the electrical data plate indicates a different voltage, call your dealer immediately. DO NOT, UNDER ANY CIRCUMSTANCES, CONNECT THE AC/DC ADAPTER OR SWITCH ON THE PRINTER. Make sure that the plug on the mains power cable of the AC/DC adapter is of the type accepted by the mains socket you intend to use; if it is not, call your dealer. ! Do NOT attempt to change the plug yourself. Make sure the printer is switched OFF BEFORE plugging the AC/DC adapter into the mains power socket. Printer Switch-On After checking ALL the previous points, and ONLY if no further intervention is required, plug the AC/DC adapter into the mains power supply and switch on the printer (the Power On LED lights). ! The on-off switch on the printer does NOT control the power supply to the printer. To disconnect the printer from the power supply, you must unplug the AC/DC adapter cable plug from the mains socket. Whenever the printer is switched on: It undergoes a series of internal checks. If any faults are found, the ON Line LED on the operator panel will flash rapidly. Should this happen, switch the printer off and then on again. If the fault persists, call your dealer or the technical assistance service. A mechanical reset is executed and the printer restores the last-saved user-programmed parameters - Printer Programming section (the very first time the printer is switched on, the factory default values for the programmable parameters will be loaded). The print head carriage stops in the extreme left-hand position (rest position). If no faults are found, it will be in ON LINE condition (On Line LED lit). If you have had any problems, check that you have executed all the procedures described in this chapter correctly; if you have, see the section entitled "Troubleshooting." Ink Jet Print Head Insertion When the printer is not powered or idle, the print head carriage is locked in its rest position (at the extreme left). ! Do NOT try to move the print head carriage manually. The carriage lock is released by an internal motor prior to any printer operation. To insert the print head: With the printer already switched on, press the Economy/LQ key for at least three seconds to position the print head carriage in the head loading position on the carriage shaft before opening the front cover. Open the front cover of the printer. Open the sealed print head container and remove the protective cover. Remove the print head from its container, holding it by the casing (the area at the opposite end from the protective film). Do not touch the electrical contacts or set the print head on them. Still holding the print head casing, remove the protective film. Do not touch the printing nozzle or set the print head on it. With the electrical contacts towards the corresponding contacts in the housing on the print head carriage, insert the print head in its chamber, tilting it towards the contacts and then pushing it down to fix it in place. Make sure the print head is inserted and fixed correctly. If necessary, repeat the insertion operation. Do NOT push in the print head horizontally; if presented correctly for insertion, it only needs to be pushed down gently into place. Close the front cover Press any key on the operator panel to return the print head to its rest position, before starting a printing operation. If you have problems inserting the print head: Make sure the print head carriage is in the head loading position (slightly to the right of the center of the carriage shaft). Check that the print head chamber is clean and free of foreign objects. NEVER force the print head into the chamber. If you have problems when inserting the print head, always remove it completely and repeat the entire insertion operation. Ink Jet Print Head Removal The ink jet print head is removed either to replace it or to repeat its insertion (see the section entitled "Ink Jet Print Head Insertion") in the case of faulty printing. With the printer already switched on, press the Economy/LQ key for at least three seconds to position the print head carriage in the head loading position. Open the front cover. Pull the black lip on the front of the print head housing slightly towards you; the print head will be released. Holding it by its casing, remove the print head from the printer. Connection to a Host System Your printer is connected to a host system (desk-top or portable computer, etc.) by means of an interface cable. The interface cable is NOT supplied with the printer. You should check with your systems manager or dealer for the type of cable suitable for your printer and computer/host system. This printer has a parallel, Centronics interface with a 36-pin female connector. Connecting the parallel interface cable Switch off and disconnect both your printer and your computer/host system from the mains power supply. Plug the interface cable connector into the socket on the rear of the printer, and close the spring clips on either side of it to hold it in place. Connect the other end of the interface cable to the appropriate interface connector socket (port) on your computer/host system. Connect the printer and computer/host system to the mains power supply and switch them on again. * For data transmission from and printer handling by the host system, see Communications Section. Loading Batteries Instead of using the AC/DC adapter and mains power supply to power your printer, you can operate it with ten LR6/AA-size 1.2 to 1.5 Volt market standard batteries available from any electrical supplies shop and most supermarkets. The batteries can be either of the disposable or rechargeable type. In the latter case, battery recharging must be done externally, using a battery recharger available from your battery supplier. To insert the batteries in the printer, proceed as follows: Remove the battery container from the base of the printer: - hold the printer vertical - with the index or middle fingers, press down on the two catches on the underside of the printer and, simultaneously, with the thumbs, push the battery container outwards. Remove any batteries from the battery container. Insert the new batteries in the battery container, making sure that their polarity is correct. Reinsert the battery container in the printer. ! The battery container must NOT be removed from the printer when you transport it. Batteries give a printing autonomy of approximately 80 pages, and should always be replaced/recharged all at the same time. Do not mix battery types and always dispose of used batteries in accordance with your local legislation. Battery state indication If the Power On LED flashes slowly, you can print only five more pages. If the Power On LED flashes rapidly, the batteries are dead. To continue printing, you must first replace ALL the batteries. Loading a Battery Pack Instead of using the AC/DC adapter and mains power supply or batteries to power your printer, you can operate it with a battery pack which is available as an option. Two types of battery pack, recognized automatically once inserted in the printer, are available: A 12 Volt, 600 mAh capacity Ni-Cd (Nickel-cadmium) battery pack which gives an autonomy of operation of approximately 80 pages. A 12- Volt, 1 Ah capacity Ni-MH (nickel-metal hydride) battery pack which gives an autonomy of operation of approximately 140 pages. To insert the battery pack in the printer, proceed as follows: Remove the battery container from the base of the printer, and keep it for future use. In its place, insert the battery pack with its contacts towards the corresponding contacts inside the printer. Make sure the battery pack is completely and correctly inserted. ! The battery pack must NOT be removed from the printer when you transport it. Battery pack state indication If the Power On LED flashes slowly, you can print only five more pages. If the Power On LED flashes rapidly, the battery pack is dead. To continue printing, you must first replace it with a new battery pack. Recharging Both types of battery pack can be recharged while in the printer; the Ni-Cd battery pack has a recharge time of approximately 6 hours, the Ni-MH battery pack, 12 hours. With the printer connected to the mains power supply using the AC/DC adapter and switched on, battery recharging can be started: Manually (by pressing On Line for more than 3 seconds), the battery pack will be recharged as long as the printer is idle. When the printer receives an operating command, recharging will automatically be suspended, to be resumed as soon as the printer is idle again. Automatically, when a low battery condition is detected. If the Form Feed and On Line keys are pressed simultaneously, recharging will stop and the printer will be set ON LINE. Take care not to continually recharge or overcharge the battery pack, as this will adversely affect its operating life. Fast recharge A universal power supply combined with a fast battery pack recharger is available as an option (see Appendix C). This device, which you connect to your mains power supply, guarantees safe, efficient battery pack recharging, reducing considerably the recharge time and preventing overcharging. Using the fast recharger, the Ni-Cd battery pack can be recharged in approximately 40 minutes, the Ni-MH battery pack, in approximately an hour. If there is a temporary interruption of the mains power supply, recharging will be resumed automatically when mains power is restored. During the recharge operation, the three LEDs on the operator panel flash in sequence. As the printer and the battery pack warm up considerably during the recharging process, make sure there is adequate natural ventilation. The outer cover of the printer should, if possible, remain open during recharging. Do not disassemble used battery packs and always dispose of them in accordance with your local legislation.
