This error code indicates that the Magenta Laser Scanner (the unit that controls the functions of Magenta) is having a problem. There's not much you have to do, if there's no mechanical or physically damaged components, following these steps will fix your problem. Remove all the cartridges, drum and the fuser unit, turn off the machine and leave it Off for few minutes. Also unplug all the cables attached to the machine including the power cord. Clean whatever is possible like the chips on the cartridges/drum, contacts (point of contact with the cartridges and drum) on the printer. Press the power button and the cancel button several times. After it's done and all the components are cleaned, turn on the printer, install all the units/components you've removed and check again. If possible, try with another Magenta cartridge.

If you have old cartridge with working chip, you can put it on the Magenta cartridge and try.

In most cases, cleaning and turning On/Off fix, but if in case it's not helpful, there must be another internal issue with the machine.

Don't forget to press the cancel button while the machine is booting up and keep pressing the cancel button while you install the cartridges.

There is no other solution except these, and hp will also tell you to call their technical support. You can contact Hp from the options listed here (click here)

    Sorry, for the delayed response, I took a break. Actually, you cannot open the front tray and the closure before you disassemble the other components, you can only open it and may be able to pull out a bit. But you can pull out the fuser completely (click here for tutorial). There's no other way to open the back cover unless you open apart the machine and remove the screws. The only thing you can do is, remove the fuser, open the front door, and give a hard blow using a blower. Please don't try to open it, there are many gears inside and once you open it, they may unlatch themselves and you'll end up frustrated.

    Honestly I hate this Hp series, but what can we do, you've got it and it should be fixed somehow.

    (we can buy another good [but smaller] laser printer/model with the price of all the cartridges and drum, they are too expensive and it makes us difficult to troubleshoot since we'll loose several 100s bucks if it's not successful)

    If it's under warranty, don't try anything more than what i've mentioned, you'll not be able to claim.

    Once again I wish you good luck.

    Thanks for using FixYa.

    You can directly contact Hp, if their Tech are available in and around your locality/area, they'll send you their man/men to inspect your machine.

    Use this form (click here), open this link, provide/select the suitable/applicable info/location, click "Next", since your item is printer, you'll not be able connect them directly, you'll need to provide some more info about the product/printer like "Product Number" and "Serial Number" (click here to read how to find out the product info). You'll be presented with a live chat window, you will need to wait for the representative to attend your request.

    You can also try calling this number 800-752-0900 (for general inquiries only) and get help from them.

    For now, I could only wish Good luck.

    Thanks for using FixYa.

Problem Error Code 54.OC.01 For HP Color LaserJet 3600 Printer

If the error won't go away, the DC Controller in the printer will have to be replaced.
The ".0C.01" part of the error can't be found in the service manual, but I don't think that it will change the fix.

HP Laserjet 3600n doesn't match screen color

Check the levels for your Magenta cartridge and replace if necessary.

Otherwise, Enter the properties of your printers driver in the control panel and establish if there is any advanced color management being used.

Let us know if you need anything else.
