However, as with all electrical equipment certain precautions should be allowed: ➢ Read all documentation supplied with and on the printer before commencing. ➢ Always disconnect the printer from the mains source before cleaning. ➢ Be certain that your power source matches the rating listed on the back of the printer.
Important Wiring Instructions The wires in the mains lead are coloured in accordance with the following code: Green and Yellow Blue Brown Earth Neutral Live If the colours of the wires in the mains lead of this printer do not correspond with the markings of the terminals of your plug, proceed as follows: Green and Yellow must be connected to the terminal marked with the letter E (or the safety earth symbol) or the terminal coloured Green or Green and Yellow.
Installing Your Printer Prior to unpacking the printer, find a flat, sturdy surface to place it on, for example, a desk, printer stand, etc. Gently remove the printer from its carton. Make sure you have everything shown below: ➢ ➢ ➢ ➢ ➢ MICROLINE 320/390 FLATBED printer Sheet stacker Power cord Ribbon cartridge Printer Handbook ! Note: Save the box and all packing material. Repack the printer when planning to transport it long distances, in order to protect it from rough handling and damage.
Preliminaries Before plugging in the printer, follow these steps to install your printer. 1. Hold both sides of the access cover and lift up. There is a shipping retainer to protect the printhead from jamming. Remove this shipping retainer and keep it with the other packing materials. (To transport the printer long distances, make sure to re-install the shipping retainer). Close the access cover.
2. Next install the sheet stacker. Put the stud of one of the stacker’s legs into the hole at the end of the rear vent. Gently press the other leg until it slips into the other hole. 3. Make sure the power switch is OFF. Plug the power cord into the back of the printer. Plug the other end into an earthed socket. 4. Turn the power switch on, and check that the POWER lamp and the ALARM lamp are illuminated. If paper is loaded, the POWER lamp and the SEL lamp will be illuminated.
5. Turn the power switch off. ! E–8 Important: Make sure the socket is earthed. Do not use an adapter because it will defeat the earthing.
Connecting to the Computer These instructions are for the standard centronics parallel interface. 1. Make sure that both the printer and the computer are switched OFF. Wire clips Parallel interface cable Parallel interface connector 2. Plug the interface cable into the port on the back of your printer. Fasten the the cable using the wire clips that can be found on both sides of the connector port. 3. Plug the other end of the cable into the printer port of your computer.
Installing the Ribbon Cartridge 1. Set the headgap lever to the “R” position. 2. Open the access cover. 3. Slide the print head gently towards the centre to give yourself some working room. There is a cut-out at the centre of the sheet guide for changing cartridges. Headgap lever Printhead Sheet guide Cut-out ! Important: a) The printhead gets very hot during extended periods of printing, be sure to let it cool off before you touch it. b) Make sure that you are using the correct ribbon.
5. Insert the flat end of the cartridge into the upper part of the ribbon plate, then lower the front of the cartridge over the printhead until it snaps into place. Ribbon plate Blue take-up knob 6.
