HP Designjet CP Series Printers - Cleaning and Maintenance

Normal printer use
"Normal" printer use means an average of 15 image prints with an area of 0.76 square m/print (8 square feet /print) per day. If your drawings are smaller than this, the number of pages per day can be higher. The HP Designjet CP series printer keeps an internal count of total usage.
Under normal usage conditions, it will be approximately five years before general maintenance is required. Operating the CP series printer more than this, the printer will require general maintenance sooner and more frequently. When the usage has exceeded the amount where maintenance is required, the front panel will display the message: Status Maintenance advised.
When the Maintenance advised message is displayed, contact your local HP dealer or HP service engineer to arrange for maintenance service.
 note:
If your unit is still under warranty or if you have purchased an HP Support Pack or HP Service Contract, this maintenance is covered without extra cost.
After the maintenance service, the message will disappear. If you choose to ignore the message, you can continue to use the HP Designjet CP series printer as normal but may encounter operational or print quality problems.
 warning:
To avoid an electric shock, make sure that the HP Designjet CP series printer is switched OFF and unplugged before attempting to perform any maintenance procedures. Do not let water get inside the printer.
Lens maintenance
The optical sensor on the printhead carriage has a lens cover to protect it from ink aerosol and other contaminants. The lens cover is located on the lower right side of the carriage. Over time, this lens cover will get dirty and need to be replaced. When the HP Designjet CP series printer detects that the lens cover is dirty, it will display the message: Status Lens Maintenance.
You should replace the lens cover to prevent any problems with printer operations due to the optical sensor. Replacement lens covers are provided with your printer and are stored inside the right door of the printer. Replace the lens cover immediately when the message occurs, or wait until the next time an ink system is replaced.
Replacing the lens cover
Follow these steps to replace the lens cover:
  1. Press the Replace Ink System key on the front panel.
  2. When the printer carriage stops and the front panel displays the message Open window to access print heads, open the window of the printer.
     note:
    Do not open the window before the Open window to access print heads message is displayed.
  3. The printer will display the message: Replace lens cover Continue----------------->.
  4. Remove the dirty lens cover from the printhead carriage by pulling it straight out of the slot on the right side of the printhead carriage.
  5. Take a new lens cover from inside the right door of the printer. The message Close right door to continue will be displayed when opening the door. Close the door after removing the new lens cover.
  6. Make sure that you do not touch the glass portion of the lens cover. Install the new lens cover into the slot, and make sure that the cover is firmly in place.
  7. Press the Down Arrow key on the front panel. The process is now complete.
What to do next
The printer will now prompt you to replace the ink system components, starting with the message Replace Print Heads. You may now replace the ink system, if necessary. If not replacing the ink system, do the following:
  1. Close the printer window.
  2. When the printer displays the message Open right door to access head cleaners, open the right door of the printer and then close it.
  3. When the printer displays the message Open left door to access ink cartrg, open the left door of the printer and then close it.
The printer will display the message STATUS Checking ink system and check the ink system components. When the message STATUS Ready is displayed, the printer is ready to print.
Cleaning the printer exterior and inside the doors
Clean the outside of the printer, as required, with a damp sponge or a soft cloth and a mild household cleaner such as a non-abrasive liquid soap.
Over time, aerosol spray from the print heads may build up on the inside of the left and right access doors and inside the printer window. This aerosol buildup can be cleaned with a damp sponge or a soft damp cloth and a mild household cleaner such as non-abrasive liquid soap.
 caution:
Do not use abrasive cleaners on the printer.
Storing and moving your printer
If you need to move the printer or store it for an extended period of time, you need to prepare the printer properly to avoid possible damage. To prepare your printer, follow the instructions listed in the following sections.
  1. With the front panel displaying Ready, press Enter.
  2. Using the Arrow keys, scroll to Utilities and press Enter.
  3. Scroll to Transport mode and press Enter. The printer displays the message Accessing print heads while moving the printhead carriage to the unloading position.
  4. When instructed open the top cover and remove the printheads.
  5. Open the printhead cleaner access panel and remove the printhead cleaners.
     warning:
    When opening the right door of the printer, the printhead cleaners move to the front of the printer for removal. Keep hands clear of the opening until the printhead cleaners stop moving.
  6. Now open the ink cartridge access panel and remove the ink cartridges.
     caution:
    Never pull the ink cartridge out by the tube or connector. This may cause the ink cartridge to leak. Always grasp the body of the cartridge when removing or installing.
  7. Turn the printer off.
  8. Disconnect all cables (power cable, parallel cable, network cable).
  9. The printer is now ready for transportation or storage.
