HP color LaserJet 5500 Paper jam recovery - Diagnostic mode - HDD initialization - Cold reset procedure


Enabling memory (HP Color LaserJet 5500 models)
If you installed a memory DIMM, set the printer driver to recognize the newly added memory.
1. On the Start menu, point to Settings, and then click Printers or Printers and Faxes.
2. Select this printer and select Properties.
3. On the Configure tab, click More.
4. In the Total Memory field, type or select the total amount of memory that is now installed.
5. Click OK.
Enabling the language font DIMM (HP Color LaserJet 5500 models)
If you installed a language font DIMM in the printer, you must select the Font DIMM option in the printer driver for the font DIMM to work properly. To enable fonts from the PCL 5c and PCL 6 printer drivers for Windows, follow this procedure:
1. On the Start menu, point to Settings, and click Printers.
2. Select this printer and select Properties.
3. On the Configure tab, click More.
4. Select the Font DIMM check box.
5. In the Configure Font DIMMs dialog box, click Add to add the font file.
6. In the Add Font DIMM dialog box, browse to the location of the font file, select the font file, and click OK.
7. In the Configure Font DIMMs dialog box, select the installed DIMM.
8. Click OK.
Paper Jam recovery
This option allows you to configure the printer response to paper jams, including how it
handles the pages involved. AUTO is the default value.
# AUTO -The printer automatically turns jam recovery on when sufficient memory is available.
# ON -The printer reprints any page involved in a paper jam. Additional memory is allocated to store the last few pages printed, and this might cause overall printer performance to suffer.
# OFF -The printer will not reprint any page that was involved in a paper jam. Since no memory is used to store the most recent pages, performance might be optimal.
To set jam recovery response
1. Press (HP Color LaserJet 5500 models) or MENU (HP Color LaserJet 5550 models) to enter the MENUS.
2. Press TICK to highlight CONFIGURE DEVICE.
3. Press DOWN to select CONFIGURE DEVICE.
4. Press TICK to highlight SYSTEM SETUP.
5. Press UP to select SYSTEM SETUP.
6. Press TICK to highlight JAM RECOVERY.
7. Press UP to select JAM RECOVERY.
8. Press TICK or to select the appropriate setting.
9. Press UP to set the selection.
10. Press MENU.
LED diagnostics
Use the following procedure to help identify the cause of high-level printer problems. These problems are indicated by abnormalities in the printer's power-on sequence. The LED that the procedure refers to is on the formatter. This is a “heartbeat” LED that blinks on and off when the formatter is operating correctly.
1. Does the LED blink with four fast bursts at power on 
If not, then perform the following checks.
# Check the firmware.
# Check the memory.
# Check the formatter.
2. Does the LED blink at a fast, steady rate during memory testing (one blink per 8 MB) If not, then perform the following checks.
# Check the control panel display for an error code.
# Check the memory.
# Check the formatter.
3. Is the LED off for about eight seconds, while the boot code is decompressing, before the display turns on. 
If not, then perform the following checks.
# Check the firmware.
# Check the control panel display for correct connections and operation.
# Check the control panel display for an error code.
4. Does the LED blink at a steady rate of one blink per second
If not, then perform the following checks.
# Check the firmware.
# Check the formatter.
# Check the control panel display for an error code.
5. If the control panel display does not illuminate, perform an engine test to check the engine. You must have paper loaded in Tray 2 for the engine test.

Engine diagnostics
This section provides an overview of the engine diagnostics incorporated into the HP Color LaserJet 5500 series printer. The printer contains extensive internal diagnostics that help in troubleshooting print quality issues, paper path issues, noise issues, component issues, and timing issues.
Diagnostics mode
Some of the diagnostic tests automatically put the printer into a special diagnostics mode.
The special diagnostics mode allows the printer to perform actions that it normally could not because the printer would enter an error state. Always follow the control panel directions in the Diagnostic menu to properly exit the special diagnostics mode and return the printer to a normal state.
Diagnostics that put the engine into the special diagnostics mode
There are three diagnostic tests that put the engine into a special state:
# Disable cartridge check
# Sensor test
# Component test
While the printer is in the special diagnostics mode, the display should read:
Ready Diagnostics mode
To exit, press CANCEL JOB for the HP Color LaserJet 5500 or STOP for the HP Color LaserJet 5550.
When the printer is in the special diagnostics mode, the three tests listed above appear in the menu and are available to be run. To access other diagnostic tests or to leave the special state, press the CANCEL JOB button (HP Color LaserJet 5500) or STOP (HP Color LaserJet 5550), and then select EXIT DIAGNOSTICS. The printer will reset itself, and then return to the normal state.
To access the main menu and get to the diagnostics menu when the engine is in an error state, such as when a cartridge is missing, you do not have to turn the printer off and then on again or resolve the error state before proceeding with the diagnostics tests. Simply open the top cover to release the door switch, which will allow you to navigate the main menu and access the diagnostics menu.
Diagnostics tests
Different tests can be used to isolate different types of issues. For component or noise isolation, you can run the diagnostics with the covers removed. Removing the rear cover, top cover, rear top cover, and side covers provides a better view of the areas being tested. To operate the printer with the covers removed, defeat the door switch (SW1, callout 1) and depress the ETB connector (callout 2) after closing the ETB.
Take caution when performing printer diagnostics to avoid risk of injury. Only trained service personnel should access and run the diagnostics with the covers removed. Never touch any of the power supplies with the printer turned on.
Door switch and ETB connector
Any time a cartridge is installed or removed while the covers are removed, the door interlock must be cycled to simulate opening and closing the top cover in order for the engine to recognize the change. The ETB must be closed and its connector must be depressed before cycling the door switch, or the printer will generate a 59.90 Printer Error. With covers installed, the door switch and ETB connector are automatically operated. With covers removed, you must manually perform these steps.
Cold reset
A cold reset unlocks menus that have been locked and resets variables in the control panel. However, it does not clear the values in the Service menu (such as the serial number and page counts).
To perform a cold reset
1. Turn the printer on.
2. As the printer performs its power-on sequence, press TICK and hold until all three lights on the control panel are lit.
3. When Select A Language appears on the display, press UP until COLD RESET appears on the display.
4. Press TICK . The printer will perform a cold reset and then continue its power-on sequence.
NVRAM initialization
Initializing NVRAM will reset the serial number, the event log, the page counts, the calibration settings, and the EIO card. Use the Service menu to restore the serial number and page counts. You will also need to reconfigure any computers that print to this printer to recognize the printer. Initialize NVRAM only when absolutely necessary. In most situations, use Cold reset to reset printer variables but still retain the needed values in the Service menu.
Before initializing NVRAM, print a configuration page and a supplies status page to gather The following information:
# Total page count and color page count
# Transfer kit count
# Fuser kit count
# Serial number
To initialize NVRAM
1. Turn the printer on and watch the control panel display.
2. When the display begins showing the memory count, press and hold until all three lights on the control panel are lit.
3. Press UP
4. Press PAUSE/RESUME for the HP Color LaserJet 5500 or press STOP for the HP Color LaserJet 5550. The display should show SKIP DISK LOAD.
5. Press UP until NVRAM INIT is highlighted.
6. Press TICK The printer will initialize NVRAM and then continue its power-on sequence.
Hard disk initialization
A hard disk initialization will erase and reformat the printer’s hard disk. Perform hard disk 
initialization only if an error code appears on the control panel indicating an EIO disk error.
Always try initializing the hard disk before replacing it.
To initialize the hard disk
1. Turn the printer on.
2. When the Memory Count appears on the display, press and hold the MENU button.
3. When the LED's are all on and steady, release the MENU button.
4. Press and release the RETURN button. You should now see INITIALIZE DISKS on the control panel.
5. Press and release the TICK button.
