What max stock paper thickness can the PRO 6978 haandle?

[ULIULI]

I am trying to print on a business card paper that is 10 mils thick. The printer has problems feeding the paper in and aligns it up poorly. I don't know if there is an adjustment for that. I think the thickness is the culprit. To test it, I sanded the leading edge, so as to reduce the thickness to 8 mils or less. This seemed to work. The paper went in all the way to its stopping point and aligned it correctly. The problem I have I can not find business card paper that is a little thinner.  Avery and Staples only carry 10 mils thick. I measured them

Paper weight may indeed be the problem - and no, if the paper is too heavy, there is no workaround.

 Printer Specifications for HP OfficeJet Pro 6900 Printers

Paper tray capacities

To avoid paper jams and other issues, do not overload the input tray.

Tray	Type	Weight	Capacity
Input tray	Paper	60 to 105 g/m2 (16 to 28 lb bond)	Up to 225 sheets of plain paper
Photo paper	200 to 280 g/m2 (60 to 75 lb bond)	Up to 60 sheets
Envelopes	75 to 90 g/m2 (20 to 24 lb bond envelope)	Up to 10 envelopes
Cards	163 to 200 g/m2 (90 to 110 lb index)	Up to 60 cards
Duplexer	Paper	60 to 105 g/m2 (16 to 28 lb bond)	n/a
Automatic document feeder (ADF)	Paper	60 to 90 g/m2 (16 to 24 lb bond)	35 sheets
Output tray	Paper	60 to 105 g/m2 (16 to 28 lb bond)	Up to 60 sheets of plain paper (text printing)

note:

Output tray capacity is affected by the type of paper and the amount of ink you use. HP recommends that you empty the output tray frequently.

Avery 5371 = 216 gsm

Avery 28878 = 254 gsm

Avery 8371 = 230 gsm

Avery 8871 = 254 gsm

The printer can handle up to 280 gsm photo paper - but it is generally not possible to trick the printer into printing on card paper after having told it (necessarily) that the paper in the tray is photo paper.  

That said, my previous two Officejet Pro printers and my current OfficeJet Pro 9025 claim the same restrictions for "card" paper weights.

Even so:

I have successfully used Media type = Brochure matte with Avery 8871 business cards.

Brochure paper (HP) is 180 gsm.

So, what to do?

Unknown...

Try the Media type suggested

and / or

If you can get a hold of Avery 5371 (at 216 gsm) and select Media type Card or Brochure, it might work.

Thanks for your input on options. I will try them out. For the moment I will use my jig to sand off 2 or 4 mils of the leading edge of the card paper of my existing supply.

@ULIULI 

You are welcome.

Based on what is in the Specifications, it makes sense to use what you have if you can make it work.

The world is already full of paper - we should use our good paper when we can do so.

Happy Printing.
