conflict between old and new printer

[louisenedela]

I am resuming use of this printer ( M234) after being out of State for 6 months.  I bought a new printer (same model as my old one, M235) and I use the new printer 6 months in another state.  I had problems trying to coordinate instant ink (toner) for both printers, so I cancelled the M234 instant ink, thinking I would resume it when I returned.  I have an instant toner cartridge for M234 that was delivered while I was out of town.  I installed the cartridge, but it will not work: after research, I found out it cannot be used because I canceled my Instant Ink account.  I have ordered a new toner cartridge, but I would like to get back on Instant Ink.  Is that possible?  What can I do about this?

Hi @louisenedela,

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 you are resuming use of your HP M234 printer after being away and want to reactivate Instant Ink, but your previously delivered cartridge cannot be used because the Instant Ink account was canceled. Let’s go through your options.

a. Reactivate Instant Ink for Your Printer

You can re-subscribe to Instant Ink for the M234 printer at any time via HP Instant Ink website.

Sign in with your HP account and follow the steps to add your printer back to the subscription.

b. Use a New Instant Ink Cartridge

After re-subscribing, you will need a new Instant Ink cartridge that is valid for your account.

The previous cartridge delivered while your account was inactive cannot be activated, so it must be replaced.

c. Canceling/Managing Multiple Printers

Since you also have an M235 printer, HP Instant Ink typically allows one account per printer.

If you want both printers on Instant Ink, you’ll need to manage subscriptions separately for each printer.

d. Using Standard Cartridges Temporarily

If you receive the new standard toner cartridge for M234 before Instant Ink is reactivated, you can use it temporarily.

Once the Instant Ink subscription is active again, you can replace it with an Instant Ink cartridge.

I hope this helps.

Thanks for your reply.  I have had no luck whatsoever in trying to get help with this problem.  When I used the M235, I would continually get messages that the "printer was offline".  I don't remember now what repercussions that caused, but it was a headache.  There was an option to "add another printer'", however, those instructions did not work.  I finally received one reply for help; however, it was a man who was apparently using a translator, and he couldn't speak English.  I got no where.  I finally decided to cancel the M234 Ink plan, not take one out on the M235, buy a new cartridge for the M235, and when I returned home, I tried to install the cartridge that I received long agol.

However, I had to buy a cartridge last year, because someone at HP made a mistake in my account, and I ran out of ink.  I did talk to someone then, asking them not to send a cartridge because I already had one.  But the cartridges kept coming, and I always had an extra one.  I think it was that extra one that I just installed and it was rejected.

Anyway, this appears to be so convoluted that I think I will just buy a cartridge for each printer when I need it and not join the Ink Plan.  It appears the monthly price is comparable to buying a new one when I need it.

This has been unpleasant, but mostly because I could not get help from HP.  I put in many hours attempting that, and went around circles each time.  I really like these printers, and I sincerely hope there are no more problems. 

 I trust that using my own purchased cartridges will not be thwarted in any way to using the printers.  Please reassure me of that.

PLEASE CONFIRM that I will NOT resume the instant ink.  Please see my comments below.

Hi @louisenedela,

Thank you for your update. I understand your HP M234 printer is showing ER 75 after installing a new non-Instant Ink toner cartridge, and you want to confirm that you will not resume the Instant Ink subscription. Let’s address this clearly:

a. ER 75 Cause
 - This error usually occurs when the printer detects a mismatch between the cartridge and the printer’s Instant Ink subscription status.
 - Since your previous Instant Ink cartridge was tied to a canceled account, the printer may still be expecting an Instant Ink cartridge.

b. Using a Standard HP Toner Cartridge
 - Ensure the new cartridge is an official HP standard M234 toner cartridge (non-Instant Ink).
 - Remove the cartridge and reinstall it firmly, making sure the protective tape is fully removed.
 - Power cycle the printer: turn off, unplug for 60 seconds, then power on.

c. Reset the Printer to Clear Subscription Conflicts
 1. Go to Setup → Printer Maintenance → Restore Factory Defaults (or similar menu).
 2. Confirm the reset. This clears previous subscription references.
 3. Reinstall the standard toner cartridge.

d. Verify Printer Firmware
 - Make sure the printer firmware is up-to-date. Outdated firmware may block new standard cartridges after Instant Ink.

e. ER 75 Persists
 - If the error continues, remove the cartridge, power off the printer for 5–10 minutes, then reinstall the cartridge.
 - Make sure no leftover Instant Ink cartridge remains in the printer.

I hope this helps.
