I can't print envelopes using Word on my HP8710 printer

[PAnastasi]

I create an envelope in Word. I set all the options for a #10 business envelope. I load the #10 envelopes into the HP8710 paper tray, adjusting the paper guides. I hit print. I hear the printer activate. It starts to load the envelope. Then the printer stops and I get the following message on the printer screen:

"The paper size detected by the printer does not match the paper size selected (Letter (8.5x11in.)) for the print job. Make sure the paper size is correct to continue the job. Touch X to cancel."

However, I have set the printer options correctly, and loaded the envelopes correctly.

I have even tried uninstalling and reinsCan anyone help me, please?

Hi @PAnastasi,

I'd like to help!

To assist better -

1. Are you able to make standard copies?
2. Have you printed regular documents from the computer? Have you received the error with other paper types/size?

Meanwhile, you may try the below steps to print envelopes

1. In Microsoft Word, click Mailings, then click Envelopes.

   NOTE: 

   To use advanced Mailings tools to print multiple envelopes and use the Mail Merge feature, go to Microsoft Office: Mail merge with envelopes (in English).

   

2. In the Envelopes and Labels window, type the address in the Delivery address field, then type in the return address in the Return address field.

3. Click Preview.

   The Envelope Options window opens.

4. Select the envelope size and change the font type and size, if necessary.

   

5. Click the Printing Options tab, select the feed method and the tray based on your printer type, then click OK.

6. Click Print

Hope this helps! Keep me posted.

Thank you for the reply. 

Yes, I regularly print to this printer using standard 8-1/2x11 paper, with no error messages or problems.

I have also tried the exact measures you suggested for printing envelopes, step by step. No luck, unfortunately

And, as I said earlier, I have even tried deleting the printer and reinstalling it using the latest software and drivers from the HP site.

However, the error message continues to appear on the screen and I can't print envelopes.

Any other thoughts would be appreciated.

Apologies for jumping in unannounced.

If you have not done so,

Make sure the printer itself knows what you are doing, that is, adjust the paper on the printer display panel.

Check / Adjust the settings in the Embedded Web Server (EWS) for the paper.

Example - Printer Display - EWS Tray and Paper - Set Preferences

Retain_Printing_Preferences_1

Example 2 - Embedded Web Server (EWS) > Settings Preferences > Tray and Paper Management

EWS_9025_Preferences_Tray_and_Paper_Management_All_3

Example 3 - Windows - Word > Mailings > Envelopes - #10 envelope
