HP OfficeJet Pro 7740 Questions & Answers

According to HP's paper handling specifications for this printer, the maximum thickness is 180gsm. At a guess I would place the paper in one of the paper trays as per normal. I suggest going into printer properties, select Printer Preferences and select the appropriate paper type from the list for the particular print job. Hopefully that helps.

It is my understanding that the 7740 uses chip technology that may prevent the use of other than genuine HP ink cartridges. I read some documentation (from HP) that the authentication is that tight that even re-using previously installed HP cartridges may present a problem.

From an HP manual (Officejet 86xx family):
Printing with black or color ink only
For regular usage, this product is not designed to print using only the black cartridge when the color cartridges are out of ink.

However, your printer is designed to let you print as long as possible when your cartridges start to run out of ink.

When there is sufficient ink in the printhead, the printer will offer you the use of black ink only when one or more of the color cartridges are out of ink, and the use of color ink only when the black cartridge is out of ink.

The amount that you can print using black or color ink only is limited, so have replacement ink cartridges available when you are printing with black or color ink only.

When there is no longer sufficient ink to print you will get a message that one or more cartridges are depleted, and you will need to replace the depleted cartridges before you resume printing.

CAUTION: While ink cartridges are not damaged when left outside of the printer, the printhead does need to have all cartridges installed at all times after the printer is set up and in use. Leaving one or more cartridge slots empty for an extended period may lead to print quality problems and possibly damage the printhead.

Unfortunately NO

Bummer! Thank you.

Yes it does single sided, from the flatbed only, using the Windows Fax and Scan app. The ADF is for A4 only. Unfortunately the HP app only recognises A4, which is why I use the one that ships with Windows (under Windows Accessories on the menu bar).
