HP Designjet T1120 Printer Series - Replace the cutter

Replace the cutter

The cutter may need to be replaced once or twice during the life of the printer, depending on the total amount and thickness of paper used. The front panel advises when replacement is due. If you do not replace the cutter immediately, the printer continues working normally, but the front panel continues to remind you about the cutter.
To replace the cutter:
  1. If there is paper loaded in the printer, unload it.
  2. At the front panel, select the Setup menu icon , then Resets > Reset cutter life counters.
  3. After a brief pause, the printer turns itself off. The printhead carriage is parked on the right-hand side of the printer, and the cutter on the left-hand side.
      waarschuwing:
    There is a risk of electric shock if you attempt to replace the cutter with the printer turned on.
  4. Lift the ink cartridge cover on the left-hand side of the printer.

    The two wheels on the bottom of the cutter should engage the central ridge on the cutter rail, and the two bushing guides should fit into the groove in the upper part of the cutter rail.

    Check that the cutter runs smoothly up and down the rail. You can leave it anywhere on the rail; the printer will park it correctly later.
  11. Fit the cutter stop onto the end of the cutter rail, holding it there with one hand while you tighten the screw with the screwdriver in your other hand.
