Paper too long to support two-sided printing

[xyz22]

On our year old HP Officejet Pro 8715 All-in-one printer after 9 months of printing 2 sided documents correctly we are now getting a "Paper Too Long" message and some of the 10 copies are printing correctly but others are printing on one side only. this appears to be random!

we are using A4 paper that is correctly positioned in the tray.

thanks

It might be time to clean the printer.

Quality - Solutions and how-to clean the printer included here:

•  Black or Color Ink Not Printing, Other Print Quality Issues

If you ever do change the paper in the printer, for example, if you sometimes use other than the A4 paper, remember to tell the printer about the paper size / type change.

Check / Adjust / Retain the Paper at the Printer Panel

Open Printer Tray,

If you have not yet done so, add desired paper type

Close Tray

IF applicable for your printer:

Look for a message on the Printer Control Panel,

Click Modify (wording varies), set the paper size and type, Click OK

NOTE:  If the size of the Paper Size is not in the Drop-down list, Select Custom

Set the Preferences - Windows

1. The following assumes the Full Feature Software has been installed.
2. Check / enable the printer as the “Default Printer”
3. Select and adjust settings in each category for the Media (kind of paper), source (tray), and paper size.

Control Panel > icon view > Devices and Printers > Right-Click on your printer > Set as Default

Control Panel > icon view > Devices and Printers > Right-Click on your printer > Printing Preferences >

Tab Printing Shortcuts > Click / Highlight preferred shortcut > Click Apply > Click OK to exit

If the printer software supports the feature, change the settings as desired, then use “Save as” to create a Custom Shortcut.

OR

Windows key + S (search for) Printers and Scanners

Left-Click on (your) Printer > Manage >

Printing Preferences

Select a shortcut and / or set “preferred settings” for paper, source (tray), other settings

Optional (if / as available): Save As > enter a name for your custom shortcut

Click OK to save the preferences

as suggested have run print quality diagnostic and every thing fine, checked and reloaded paper and all set up correctly  as A4

Also checked windows print settings on laptop and all set correctly as suggested. Have tried printing another 2 page duplex document with 10 copies and copy 1, 3, 5, 8 and 9 failed to print double sided,  the other copies worked fine. Message on printer is 'Paper too Long'   Have tried using a different PC and getting same message and some copies failing to print double sided but not the same copies seems random which ones fail

Well, I don't know.  

I would guess the sensor in the paper tray is misreading the paper  - but that it is not happening on every copy (in a multi-copy job) does muddy things a bit.

You could try uninstalling the printer software > Restart > download-save-install a fresh copy of the Full Feature Software... This is the equivalent to "hunting for Easter eggs" - reinstalling might work if there is something going on in the software infrastructure, or it might not make any difference at all.

You could try using different paper - paper that is too dry, too damp (yes, this can be a "thing") may have trouble.  This is again simply a guess and only worth that you believe it to be worth.

Paper that is not the right weight for the "plain paper setting" might cause odd problems - but you would know if you had selected other than "plain paper" or if you are using a different Media type.

If I have anything actually useful to add, I will post back.
