Printer Printing Gibberish (Random Characters)

4.5

The printer spits out dozens of pages with random symbols and code.

Symptoms
  • Random symbols
  • Infinite printing
  • Wasted paper
Possible Causes
  • Wrong driver (PCL vs PS)
  • Corrupt print job
  • Bad cable

Step-by-Step Fix

1

Cancel All Jobs

Clear the print queue immediately to stop wasting paper.

2

Check Driver Type

Ensure you aren't using a PostScript (PS) driver on a PCL-only printer.

3

Replace USB Cable

A faulty cable can corrupt the data being sent to the printer.

When to See a Technician

Gibberish is usually the printer trying to "print" the raw code of the document because it doesn't understand the format.
