Review on 🖨️ GPC Image 201X 201A Compatible Toner Cartridge Replacement for HP CF400X CF401X CF402X CF403X CF400A - 4-Pack - Compatible with Laserjet Pro MFP M277dw M252dw M277n M252n MFP M277c6 Printer Tray by Mark Lowery

didn't want to spend $80 on HP OEM toner so I decided to give it a try. As a disclaimer, I have warned in every review I have read before about this and other non-HP brands that you may get a potential boot/initialization error. More on this in the general test report.1. The packages arrived very well. Each is packed in a box within a box. The individual toners themselves were packaged in a yellow plastic cap with protective foam around the edges upon arrival. (See Photo 1-3)2. They offer very simple and detailed instructions that also include a general troubleshooting process which leads me to believe they are at least aware that their products can cause initial hiccups here and there as it is a non-OEM branded product acts. (See Photo 4)3. It was recommended to turn off the printer when removing and installing new toner, which is what I did.4. I took out my HP branded toner and compared it to the GPC Image toner - as you can see they are very similar in all reports. (See Photo 5)5. Replaced the individual toners in their respective compartment slots where my HP toners sat in the printer's loading compartment.6. Close the toner compartment and turn the machine back on. The printer has gone through a standard restart cycle. He also noticed unbranded toners and asked me to initialize them, which I did.7. I'm getting an error message about a problem with the motor cable (never seen this before - didn't know what it was referring to) Turned the printer off, checked everything was plugged in and connected properly. And restarted the printer.8. This time the error didn't come back and it started calibrating new toners and going through its normal cycle when new toners were installed. (See Photo 7)9. Did a pressure test after all was said and done. The demo site looked pretty decent. (See Photo 8) Everything and everything except the error I got when I first turned on the printer everything seems to be working smoothly with no major issues. If you're looking for an alternative than spending $300 on HP branded toners, these might be the way to go. I will be making additional prints in the coming days/weeks and will update this review if there is anything new to note. Hope that helps.
