HP Designjet 1000 Series Printers - Switch Power Off, Check Printhead Path

Issue:
The HP Designjet 1000 series printer displays a Switch power off, check Printhead path x message, where x = 1, 2 or 3.
If the carriage consistantly stops on the left side of the printer, then refer the Document #BPP90220.
Solution
If there is nothing physical or mechanical "stopping" the printhead from moving, the problem is most likely caused by a lack of oil on the carriage slider rods, causing an increase in friction along the printhead path. The first solution is to clean and lubricate the front and rear carriage slider rods. After cleaning and lubricating, verify functionality by cycling the power and printing an internal demo print. If lubricating the slider rods does not help, follow instructions below for each individual message.
note:
Proper lubrication is important for long-term quality performance. (The expected life is 50 percent more than preceding products and more than 100 percent with correct preventive maintenance at 7.5 million carriage cycles.
To properly lubricate the carriage slider rods, please order the oil applicator, C6071-60177.
Switch Power Off Check Printhead Path (1) Shutdown (PWM Shutdown):
  • A possible paper jam (turn off the power, clear the paper jam, and restart the printer)
  • An obstacle in the printhead path (turn off the power, clear the media path, and restart the printer)
  • Overheating machine (turn off the power, allow the printer to cool, and restart the printer)
  • Scan motor left unplugged after a repair (Re-execute repair)
  • Incorrectly installed ink tubes system (Check the printer’s left side: reinstall or replace the part)
  • Failing carriage axis (scan axis) motor (Replace motor)
  • Worn carriage belt (inspect/replace belt)
  • Dirty or damaged encoder strip (clean/replace encoder strip)
Switch Power Off Check Printhead Path (2) Shutdown (velocity shutdown):
  • An obstacle in the printhead path
  • The ink tube system is worn on printers older than six months and catching the printer's left edge of its tube or front guide assemblies
  • Dirty encoder strip
  • A media/paper jam
    note:
    If the "Switch Power Off Check Printhead Path (2)" message is intermittent and does not match any case above, inspect for a worn or damaged ink tube system and/or carriage drive belt.
Switch Power Off Check Printhead Path (3) Shutdown (energy shutdown):
  • High friction in the printhead carriage path (turn off the printer, lubricate the carriage slider rods, restart the printer and verify functionality)
