Hi

59.F0 Error is displayed when primarily caused by a transfer alienation failure in which the ITB is stuck and unable to rotate or because the SR9 sensor (the primary transfer-roller-disengagement sensor aka Sensor K) has gone bad.

Steps To Be Performed

1. Reseat the ITB.
2. Check the connections to primary transfer-roller-disengagement sensor (SR9 at connector J19) and to the DC controller PCA (connector J128).
3. If the issue persists, remove the ITB completely from the unit and manually test the ITB gear and flag.
- Rotate the gear and check that the flag actuates when the white gear is turned.
- If the ITB flag is broken or damaged, or if the flag does not move, replace the ITB.

4. If the ITB gear and flag are working properly, test Sensor SR9 by using the MANUAL SENSOR TEST and manually testing the SR9 flag.
- Remove the ITB if it has been re-installed and locate Sensor SR9 inside the ITB cavity.
- On the control panel, press the Home button, press the down arrow to highlight the DIAGNOSTICS menu and press OK , and then select MANUAL SENSOR TEST and press OK .
- From inside the ITB cavity, press up and then release the SR9 flag to actuate the sensor.
- While pressing and releasing the flag, check the control panel display for sensor response (under K) and confirm that the sensor toggles between 0 and 1 (0 is the normal state).
- If the value does not toggle between 0 and 1, replace the sensor (WG8-5696-000CN).

NOTE: To stop the diagnostic, press OK , select EXIT DIAGNOSTICS , and then press OK

5 . If Sensor SR9 is working properly, perform a fuser motor (M2) COMPONENT TEST .
- Remove the Fuser.
- Defeat the right door safety switch (upper left area) by inserting a stiff or folded piece of paper and defeat the right door logic switch (right side below fuser) by using masking tape to hold switch down.
- On the control panel, press the Home button, press the down arrow to highlight the DIAGNOSTICS menu and press OK , select COMPONENT TEST and press OK , and then select FUSER MOTOR and press OK .
- During the test, observe the fuser motor gear.
- If the test fails or the fuser motor gear does not rotate, replace the fuser motor (M2).

NOTE: To exit the diagnostic, select EXIT DIAGNOSTICS and then press OK .

6.If the fuser motor is working properly, perform an ITB Contact/ Alienation Test .
NOTE: This test activates the fuser motor (M2) and primary transfer solenoid (SL1) to cycle through the ITB alienation stages.
- Defeat the right door safety switch (upper left area) by inserting a stiff/folded piece of paper and then defeat right door logic switch (right side below fuser) by use masking tape to hold switch down.
- On the control panel, press the Home button, press the down arrow to highlight the DIAGNOSTICS menu and press OK , select COMPONENT TEST and press OK , and then select ITB Contact/ Alienation Test and press OK .
- During the test, observe the alienation drive hub located above the cyan cartridge.
- If the test fails or the alienation drive hub does not rotate, replace the fuser-drive assembly.

NOTE: To exit the diagnostic, select EXIT DIAGNOSTICS and then press OK .

7. Check the connections again to the primary-transfer disengagement sensor J19 and to the connector J128 on the DC controller PCA before reinstalling the ITB.
8.Remove any items used to defeat the right door switches, reinstall the ITB and any other components removed during testing.
9.If the error still persists, replace the DC Controller.

This error is caused by a transfer alienation failure in which the ITB is stuck and unable to rotate or because the SR9 sensor (the primary transfer-roller-disengagement sensor aka Sensor K) has gone bad.

-Try reseating the ITB.

-If the issue persists, try rotating the gear and check that the flag actuates when the white gear is turned

this gear can be seen on the ITB, when it is completely removed from the unit.

- Perform a MANUAL SENSOR TEST under diagnostics menu for  SR9 flag to actuate the sensorWhile pressing - While pressing and releasing the flag, check the control panel display for sensor response (under K) and confirm that the sensor toggles between 0 and 1 (0 is the normal state).

- If the value does not toggle between 0 and 1,  the Photo-interrupter sensor has to be replaced by the onsite engineer.

Hi,

A 59.F0 error message is displayed on control panel when the product boots up if yes,

Reseat the ITB (Belt),

If the issue persists, remove the ITB completely from the unit and manually test the ITB gear and flag(White color Knob locate right side of Belt)

Rotate the gear and check that the flag actuates when the white gear is turned

If the ITB flag is broken or damaged, or if the flag does not move, replace the ITB(Belt)

Remove the Fuserand Re install again.

On the control panel, press the Home button, press the down arrow to highlight the DIAGNOSTICS menu and press OK ,

select COMPONENT TEST and press OK , and then select FUSER MOTOR and press OK .

During the test, observe the fuser motor gear.

If the test fails or the fuser motor gear does not rotate that means fuser motor is having issue 

Most of the time we found fuser drive assembly not Roted properly that why issue occuring so if issue still persist after doing above mention step you have to replace fuser drive assembly.

Thanks

this is a simple fix... I discovered that the ITB belt drive gear clutch had gotten all gummed up.. the noise surpression pad on the clutch in the fuser Drive Assemble had disintergrated and became sticky... i ordered a new Fuser Drive Gear assembly but as a time sensative Technician always looking for an easier fix i replaced the clutch only.... Problem solved...

it takes alot less time for this fix... Only the upper HVPS needs to be removed to access this part.

I have this HP CP4025 printer that the client tried to fix. Now it's reporting 59.0F errors. On inspection, 2 of the 3 tabs that lock the switch assembly in place are broken and allows the switch to float when the ITB lever elevates. The sensor is not triggering reliably.

I need the part number of the "primary transfer-roller-disengagement sensor" (Sensor K) switch assembly.

I have looked in all the manuals and asked my shop manager to contact HP with no luck so far. They sent the sensor itself (WG8-5696) but not the switch assembly.

Thanks

Hello,

<UPDATES IN RED TEXT BELOW>

The purpose of this post is to inform the community of one of the causes of and suggestions on how to resolve the 59.F0 error issue for the CP4025, CP4525 and CM4540.

<ITB Primary Transfer Roller Alienation- Sensor Flag Sticking in Up Position>

The ITB (Intermediate Transfer Belt, aka. Transfer Kit) has a feature that removes the contact of primary transfer rollers (one for each color under the belt surface) when the printer is not running to prevent sets, etc.  The printer knows the location of the transfer rollers by cycling the system and getting a response from the sensor: (K on Manual Sensor Test for 4025/4525 and SR9 on CM4540).  The ITB has a white plastic pusher (in image below) that moves the sensor flag lever on the printer (can be seen on left side with ITB removed hanging down from sheet metal cutout).  The flag passes through the photo interrupter of the sensor.  The sensor flag/lever is returned to the home postion (down) by gravity.  In some cases, the sensor flag/lever can become stuck in the up position (see image below).  When the flag/lever sticks or returns slowly the result can be a 59.F0 error.

Below is a recommended suggestion to resolve this problem:

1. Upgrade the FW
2. Remove the ITB
3. Remove the fuser and on the left side (front of printer side) you can see the sensor flag holder (image #1 and #2 below)
4. If the sensor flag/lever is stuck in the up position then reach in and carefully release the part with your fingers.  The images below show the sensor flag/lever stuck in the up position.  Actuate the flag/lever a few times to make sure it is loosened up.
5. Re-install the ITB
6. Re-install the fuser
7. Reboot to see if the error clears

If the issue returns in a short period of time, then the flag/lever is likely dragging and returning slowly or getting stuck again.  If this occurs, then it is recommended to:

1.  Remove the top cover
2. Inspect the POSITION DETECT ASSY RM1-5604 to ensure the photo interupter is seated correctly
3. Check the sensor flag for proper movement
4. Replace the POSITION DETECT ASSY RM1-5604

NOTE: The ITB is typically not the cause of this issue.

I hope this helps.

DaveK.

Just below is an image looking in with the fuser removed at the sensor flag/lever in the holder with the photo interrupter located on the left side (front of printer).  The sensor flag/lever is stuck in the up position which causes the 59.F0 error:

<Image #2>

Just below is an image looking in with the fuser removed at the sensor flag/lever in the holder with the photo interrupter located on the left side (front of printer).  The sensor flag/lever is in the down position

<Image #3>

Just below is an image of the ITB Primary Transfer Roller Alienation Pusher (white plastic part) and Sensor Flag/Lever (black plastic part stuck in the up position in the sheet metal cutout) as seen looking at the left side (front of printer) from the right side of the printer with the right door open and ITB still installed.

what is the meaning of ITB and where is it located in the printer

[SD-86]

"ITB" is the Intermediate Transfer Belt also called the "Transfer Kit".  It is accessed by opening the right door, lowering the transfer roller holder and then grabbing the blue handles to pull straight out.  The fuser or fixing assembly is accessed from the right door also, just above the ITB.
