HP Latex 800, HP Scitex LX800/LX600, HP Designjet L65500 Series - Resolving Error Code 57:11 Ink System Leakage

Disconnect the cartridge connector by pressing the tabs on each side of it and pulling it gently. Repeat for all ink cartridges.

After disconnecting all the ink cartridges, remove the front and rear ISM panels. A Torx T-30 driver is required to remove the panels.

note:

Depending on the location of the leak and the access needed for clean-up and repair, it may be necessary to remove only one panel. For maximum access, the ISM end panel may also be removed.

Input-side ISM enclosure removal. Remove this panel for access to black, cyan, and yellow components.

With the panels removed, the affected ink color is easily seen.

Clean up any liquid ink that has accumulated in the ISM tray, taking care to avoid distributing it onto any components that have not already been in contact with the ink. While cleaning, attempt to identify the specific location of the leak. The most common areas of failure are at the ink pressure sensor board, wherever a tube is attached to another component, or where two tube-ends may have been joined in a previous repair.

note:

If no ink leak can be found, there may have been a false leak detected. Continue to Cleaning the ink leak sensors.

Once the source of the ink leak has been identified, it must be repaired. Specific repairs and techniques are outside the scope of this document; search the HP Support Center for additional resources, or contact an authorized HP reseller or the HP regional Customer Care Center for additional assistance.

Power off the printer.

Locate the ink sensor near the outer end of the ISM on the rear side.

Disconnect the ink sensor and remove it from the bracket in the ISM tray.

Clean the sensor end carefully, or replace it with a spare sensor from HP spare part Q6702-60686 ISM Repair Kit, which contains one replacement sensor/cable and various other related ink system components.

All spare part information is subject to change without notice; visit HP PartSurfer for complete and up-to-date spare part information.

Start the printer in Diagnostic Mode. To start in Diagnostic mode, press and hold the Cancel button and the Down Arrow, then press and hold the Power button. Continue to press all three buttons. The LED indicator on the front panel will be steady-on red, then steady-on green, and then finally start blinking green. When the LED begins blinking green, release all three buttons.

With the printer in Diagnostic mode, use the front panel keys to navigate to 4.7 Recovery Ink Leakage. If the ink leak sensors are dry, the printer will show that the system has recovered from the ink leak.

Press any key on the front panel to finish the reset.

Restart the printer to resume normal operation.
