Zorluk: ZorPrinter and Multifunction Device Issues

A technician is troubleshooting a departmental laser printer used to print architectural drawings on heavy cardstock media. Users report that toner on the cardstock easily smudges and wipes off when touched. However, when standard 20 lb20\text{ lb} bond paper is loaded, the printed text and graphics adhere perfectly. The toner cartridge and fuser assembly were both recently replaced during scheduled maintenance. Which of the following actions should the technician take to resolve this issue?

  1. Adjust the paper type setting in the print driver and printer menu to Cardstock or Heavy Media.Cevap
  2. B
    Replace the high-voltage power supply (HVPS) board to increase drum charging capability.
  3. C
    Clean and re-align the laser scanner assembly optics to increase exposure intensity on thick paper.
  4. D
    Increase the transfer roller electrostatic voltage offset in the printer service manual firmware menu.

Cevap

Adjust the paper type setting in the print driver and printer menu to Cardstock or Heavy Media.
Cardstock and heavy paper stock absorb significantly more thermal energy than standard 20 lb bond paper. When the printer is configured for standard paper, paper moves through the fuser assembly too quickly and at too low a temperature, causing toner to sit on top of the media without fully melting into the paper fibers. Selecting 'Cardstock' or 'Heavy' media in the printer settings forces the printer to slow down the media throughput speed and raise the fuser heat, ensuring proper toner bonding.

Adım Adım Çözüm

1
Analyze the reported symptom and paper behavior
Toner adheres correctly to standard 20 lb20\text{ lb} paper but smudges on heavy cardstock.
Cardstock absorbs heat much faster than standard paper, preventing toner from reaching its melting point under default fuser dwell times.
2
Identify the component responsible for toner adhesion
The fuser assembly uses heat and pressure to permanently bond toner particles into the paper fibers.
Unfused toner can be wiped or flaked off the media after printing.
3
Select the appropriate non-hardware corrective action
Configuring the paper type to Heavy Media or Cardstock slows the feed roller pass-through speed and increases fuser operating temperature.
Proper media settings ensure sufficient heat energy transfers into thick cardstock to fuse toner completely.
