Compatible HP CE255A (55A) toner: installation guide, chip reset and savings

It is designed to replace the original consumable in HP's P3015 series monochrome laser printers and in several multifunction devices from the M521 and M525 ranges.

What it is and which printers it works with

It is suitable for exactly these models:

• HP LaserJet Enterprise 500 M525dn MFP
• HP LaserJet Enterprise 500 M525f MFP
• HP LaserJet Enterprise Flow MFP M525c
• HP LaserJet Enterprise P3015, P3015d, P3015dn, P3015n and P3015x
• HP LaserJet Pro 500 MFP M521dn and M521dw
• HP LaserJet Pro MFP M521dn and M521dw

If your device appears in this list, the cartridge fits without any adapters. See the full details on the product page.

How to install it and what to do if it says "cartridge not recognised"

Insert it until it clicks into place and close the cover.

If, after changing it, a cartridge not recognised or not compatible message appears, in most cases there is no fault: it is the chip. Try these steps:

• Turn the printer off, wait about 30 seconds and switch it back on so it re-reads the chip.
• Remove and reinsert the cartridge, making sure the metal contacts are clean and properly seated.
• If the device asks you to confirm the use of a non-HP consumable, accept it from the panel to carry on printing.

Many of these warnings come from updates that tighten consumable control. We explain how this affects you and how to prevent it in HP firmware and cartridge blocking.

Yield and savings compared with the original

The saving per page is substantial compared with the branded consumable, while maintaining a black density and text sharpness suitable for office documents.

To work out your real cost per document and compare it with your current spend, you will find the article on the real cost of printing useful. And if you want to see the differences in results, we ran an original vs compatible side-by-side test.

Why buy it from Star Toner

Your Startoner consumable is covered by a three-year legal conformity guarantee. Printer coverage is governed by the manufacturer’s terms and may exclude damage caused by consumables. Using a compatible cartridge does not by itself establish the cause of a fault; keep your documentation and contact us if a problem occurs.

And if you also manage colour devices, in the same catalogue you will find compatible alternatives such as the HP 508A CF360A toner. A well-made compatible cartridge prints the same for far less: that is the whole proposition.
