To printer 4025

The first course of action with any 49 error is to get the newest firmware installed, if the machine will come to a ready state. Unplug any USB or network cables and power cycle the printer. If it comes to ready, check any computers configured to print to ensure that no stale print jobs are stored in any print queues. (this is an important step, double check that all workstations are cleared). Once you are sure you have all queues cleared, plug the network or USB cable back in and see if printer stays are ready. If it does, go to HP.com and download the current easy firmware installation file for the 4025 and follow the instructions to update the firmware. If the machine will not come to ready even with network/usb cables disconnected then you may have a bad formatter or faulty memory on the formatter.

Replacing the Transfer Belt (ITB, Transfer Kit) HP Color LaserJet CP4525 CM4530
1. Open the printer's right side door.
2. Use the blue lever (see callout 1 in picture below) to lower the secondary transfer assembly.
3. Grasp the small handles on the transfer belt assembly (circled in blue in picture below), and begin gently pulling the assembly out towards you, until a set of 2 larger handles pop free on the sides of the transfer belt assembly.
4. Now grasp the larger handles on the transfer belt assembly, and continue pulling the transfer belt straight out of the printer until it is completely removed.
5. Avoid touching the surface of the new transfer belt. Install in reverse order, sliding it securely into the machine.
6. After replacing the Transfer Belt, it's a good idea to perform a Full Calibration (or even several Full Calibrations in a row, if you are having print quality issues). Full Calibrations help with print quality by aligning the color tones, the drums, and the color plane. Each Full Calibration takes about 4 minutes. To perform a Full Calibration: Press MENU to enter the menus. Press Down Arrow to highlight CONFIGURE DEVICE. Press Checkmark to select CONFIGURE DEVICE. Press Down Arrow to highlight PRINT QUALITY. Press Checkmark to select PRINT QUALITY. Press Down Arrow to highlight FULL CALIBRATE NOW. Press Checkmark to select FULL CALIBRATE NOW. Wait for the printer to calibrate (usually takes 4 minutes or so), and then print a test page. If print quality still needs improvement, repeat the Calibration. If multiple Calibrations don't help, some of the toner cartridges may need replacement.

Hi
probably this fuser unit is faulty, the other issue this machine uses the electric current 110 v or 220v

Pl mention which error u r getting?

Try another cyan toner cartridge. Let me know what happens. Print Quality Troubleshooting Tool for HP Color LaserJet CP4025 CP4525

compare with the old one to be sure there is no shipping tape or differences.

Its a 3 step process follow it it will fix your issue

1. Turn the printer off, and then turn the printer on.
2. Check and reseat the fuser and toner cartridge to make sure they are not hindering gear movement in the drive train.
3. Check the main motor's cable to ensure that it is seated properly. 4. If the error persists, replace the main motor.

The manual states:
59.99.00
An error occurred in the secondary transfer
engaging mechanism.
1. Faulty secondary transfer engagement
sensor. Replace the secondary transfer
engagement sensor.
2. Faulty secondary transfer engaging
solenoid. Replace the secondary transfer
engaging solenoid.
3. Faulty feed motor. Replace the feed
motor.
4. Faulty DC controller PCB
Action: Replace the DC controller PCB.

But experience shows that you should look at the Swing Plate assembly. If the gear on it is skipping, it will cause these errors. It is located in the back left under the fuser.
