This printer ran daily at a high-volume car dealership until it was retired by a software/system upgrade — not by a fault. It was then refurbished by a professional printer service technician:

  • Opened up and all internals completely cleaned
  • Printer bench tested
  • Board components bench tested
  • Confirmed functional
Condition

Very clean, professional appearance — refurbished to excellent condition. Clear acoustic cover, paper separator and platen knob all present. Photos show the actual unit and are part of the description.

Why the 321 Turbo (Wide Carriage)

The ML320 Turbo is the narrow 80-column model. The ML321 Turbo is the wide version — about 6" wider — giving a 136-column line for wide reports, ledgers, registers and oversized multipart forms, with the same 435 cps speed, built-in push tractor and zero-tear forms handling.
