Card stock feed delay into 9025 printer

[surfrasch]

Printing from 2 iMacs on Monterey, and 1 Dell laptop on Windows 10....same problem happens from each machine.

Having trouble with the card stock feed.  The card stock paper feeds into the printer, but the finishing print is missing the top roughly 3/4" of print....ie it seems the paper feeder is maybe slipping, such that it's starting to print before the paper top is under the ink jet.....assuming that's even possible?  The printer is maybe 2-3 years old roughly, worked fine a long time.....so this is a relatively new issue.

I've read through tons of posts here....

I checked my drivers, the printer says it's up to date.

I've got HP Smart, always use it.

I'm using the top tray, understood the bottom tray can't handle card stock.

I've opened everything in the printer, examined the feed rollers, can't see anything dirty, or slipping, or ripped paper screwing up the flow.

I've tried multiple setting changes on paper types, the only thing that helped align the feed was setting the paper type to photo paper.

I'm thinking it needs a "slick" paper setting to put more force on the feed.  The card stock I'm using is standard Staples product, at 110 lb and 199 g/m2....so in theory it's in spec.

I can put standard copy paper in the same upper feed tray, and it prints perfectly.....all aligned.

Any ideas?

OJ 9025 can print on cardstock it jams, 200gsm is way too above max recommended weight for paper. You are wasting your paper and ink.

The printer specifications are listed cards as supported but cards and cardstock are different.

Hi Valsimot, sorry you lost me.  What's the difference between "card" and "card stock".  I'm reading the 9025 specs off the HP web site, it lists 163 g/m2 to 200 g/m2 for "card", as well as 90 to 110 lb for "card" in U.S. units.  My "card stock" is 110 lb and 199 g/m2.  Certainly I'm at the high end of the spec, but still within it, and I think the printer needs some help to get the paper through.  Perhaps there's a slight layer of something on the rollers inside that need to be cleaned, but I'm not sure how to do this?

Cards are birthday/greeting cards and they can be printed, they have a high weight but they are easy to bend ( important for feeding paper) cardstock is heavy plain paper cardstock can't be printed because it will not bend easily.

You are wasting your paper time and ink, that printer model can't print on cardstock, check printer specifications for maximum plain paper weight everything heavier than that will only cause problems and can damage the printer.

thanks, but I need some heavier paper periodically for work and for my wife's work.....just looking on Staples web site, they show another lighter weight "card stock" paper at 65 lb and 176 g/m2.  Maybe this will work for me?  The Staples description says that it's more flexible to avoid printer jams.  Might be worth a try.

The concern is that the 110 lb paper worked for a few years, now it doesn't.

[Valsimot]

When the printer is new it can handle heavier paper but with time printer weakness ( from using too heavy paper) and just one day it will not even print on plain 80gsm paper. There is a valid reason why in printer specification is noted maximum recommended paper handling weight.

[surfrasch]

yep understood, but just to be clear, this paper is within the specification, correct?  So our assumption has to be there's something slipping or worn in the printer.

[Valsimot]

The maximum recommended for plain paper is up to 105gsm

Media weight supported (metric)

60 to 105 g/m² (plain); 220 to 280 g/m² (photo); 75 to 90 g/m² (envelope); 163 to 200 g/m² (card)

My 9025 printer will not properly pick up anything other than plain paper. 

Brochure paper both matte and glossy (hp professional business paper)

67 # card stock

Tray #1 (main tray) not at all

Tray #2 picks it up but doesn't print the whole document or card
