error 59.CO

Tried everything from on/off load cartridges.  Looks like the printer is dead.  Is it worth fixing?

Hi @razzawi,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your HP Color LaserJet Pro MFP M277dw is no longer powering on or responding, even after trying power resets and removing/reseating the cartridges
Is it worth fixing?

In most cases: No.
Here’s why:

• A formatter board or PSU replacement + labor usually costs ₹12,000–₹18,000 in India / $120–$180 in the US.
• A refurbished working M277dw often costs less than that.
• HP no longer produces key parts for this generation, so repairs are unreliable long-term.

For printers older than 5–7 years, repairs rarely make financial sense.

Before you give up, 3 quick checks just to make sure it’s not a small issue

(These cover the only “fixable without parts” issues on the M277dw.)

1. Try a direct wall outlet (no surge protector or extension)

• This model is sensitive to voltage drops.
• Plug the printer directly into a wall socket and try again.

2. Perform the hard reset

• Unplug the power cable from the back.
• Wait 60 seconds.
• Press and hold the power button for 15 seconds.
• Reconnect and try powering on.

3. Check for life signs

• Do you see any lights, display flicker, fan noise, or relay click when you power on?

No signs at all → PSU failure is likely.

Starts, then dies → formatter failure is likely.

These two parts are the ones that kill the M277dw.

Final recommendation

If the printer is more than 5 years old and shows zero signs of life, replacing it is the practical and cost-effective choice.
If it shows any flicker or partial startup, you can repair it, but only if the repair cost is under 30% of buying a new printer.

I hope this helps.
