HP Designjet 61:05 error March 12 2015, 0 Comments

System Error: 61:05

A related error is System Error: 61:05. A 61:05 generally means the firmware on the Designjet is older than what the formatter board (GL/2 accessory card) requieres. Check the firmware. If it is less than version 4, you need to upgrade the firmware in order for the newer board to work.

Designjet GL/2 Accessory Card or Formatter Board

The designjet 500, 510, and the 800 all have what are called a GL/2 Accessory Card or Formatter Board installed. Both terms refer to the same part. These board provided advance CAD features and expanded memory. It is not uncommon for them to become defective and need replaced.

The feedback I get from customers is that the main cause of the error is the printer is left on continuously. Resulting in a power surge thru the line that corrupts the ROM chip. Make sure to check your ground to neutral reading on your outlets. Faulty wiring will result in more errors.

Designjet 05:10 Error Code

If you are getting a 05:10 Error Code -- You Must Replace Your GL/2 Accessory Card or Formatter Board. A 05:10 error on the front panel of the printer indicates a formatter card failure. This issue usually does not require on-site service, as the formatter card is a user-replaceable part. It is a simple fix. The card is located on the back side nearest the power cable plug. There are two expansion cards. One is the network card. The GL/2 card is labeled and needs to be replaced. Simply unscrew it and slide out of the slot.

Part Numbering System

HP has many part numbers for the same part. They like to issue a new part number for a new lot being released for consumption. Here is a breakdown of popular part numbers. Designjet 510 model has three different part numbers: Designjet 510 CH336-60001 Designjet 510 CH336-67001 Designjet 510 CH336-80001 Designjet 500 C7772A

Please confirm that you have a Designjet 500 printer. The 500 GL/2 Card will not work in a Designjet 510 printer. I have had several customers with a Designjet 510 purchase the 500 GL/2 Card. The 500 GL/2 Card does not work in their printer. This will caused delays with exchanging the 500 card for the 510 card.

Designjet 800 has nearly ten different part numbers.
