[Musikante]

HP Office Pro 7740 does not recognize the letter size paper I have in tray 1. It gives the following message: "The paper size detected by the printer in tray 1 is larger than the paper size selected (Letter 8.5 x 11 in.)"  I tried to reset the printer, took all the paper out, same thing. The printer is brand new.

Generally, there are several places to check / adjust the paper type and paper size settings, including on the Printer display and - when the printer is on your network - using the Embedded Web Server (EWS) .  The printer software impacts the way the settings / paper is perceived, too.  Printer Software differs by Operating System.

For example...

Preparation - Windows

Printer Software

===================================================================

If you have not done so, download-save-install the Full Feature Software / Full Driver for the printer

Full Driver / Full Feature Software does not require a sign-in to use the software.

Download - save - run

 HP Easy Start Printer Setup Software

• Download-and-Save the printer software (Full Feature Software / HP Smart / Easy Start)
• Right-Click on the downloaded package and "Run as Administrator" to start the installation
• Reminder:  If using Easy Start, select the Full Driver

Easy Start...

  About 2/3 of the way through the setup, you will be given the opportunity to select the software - select the "Full Driver" set (as opposed to the basic driver).

Any...

If using USB:  Connect the cable when instructed to do so (near the last part of the driver installation)

After the software is installed, Restart the computer and log in.

Full driver provides print and scan functions supported by your printer.

===========================================================

Next...

Load the paper according to the instructions in the User Guide

Starting on Page 14

Next...

Check / Adjust / Retain the Paper at the Printer Display Panel

Open Printer Tray,

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

Wait a couple of seconds…

Close Tray

IF applicable for your printer:

Look for a message on the Printer Control / Display Panel,

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

Note:  Printer Display panel option is not applicable to printers that lack a printer display panel and might not be available on all printer models that do include a printer display panel.

Note 2 – Printer Display Panel > Adjusting the paper size:

If the size of your Paper Size is not in the Drop-down menu,

If the “custom” paper size is available in the list:

Select Custom (likely the last selection in the list)

And / Or

Embedded Web Server (EWS)

 Note:  This option is not applicable to printers connected via a USB printer cable (no network connection).

If the printer is on the network,

If the EWS feature is supported on your printer,

Use the Embedded Web Server (EWS) to view / configure your printer.

NOTE:  Laser printer options in EWS are very different from those offered in InkJet Printers.

Open your favorite browser > type / enter Printer IP address into URL / Address bar

Tab Settings > Preferences > Tray and Paper Management

If applicable, check the Advanced section (at the bottom of the Tray and Paper Management menu)

Click Apply to save changes

NOTE:  If the size of the Paper Size is not in the Drop-down menu, Select Custom (likely the last selection in the list)

NOTE 2:  EWS is also available in HP Smart Windows and HP Smart Mobile > Settings > Advanced

Set the Preferences – Windows

NOTE:  This section is not applicable to Mobile Printing.

Printing Preferences are available directly from the driver and / or might be called "Printer Properties" / "Shortcuts" (or similar) from within printing software / applications.

Notes: 

• Generally, Ignore this section when not relevant – for example, when using Word > Mailings > Envelopes.
• In the case of PDF / Image printing, Pre-set the Preferences (below) or set the Properties during the job setup.

Preferences / Envelopes

Regardless of what kind of printing you will do (later), make sure the Printing Preferences shortcut is set to "Everyday Printing" or something equally benign.  For example, don't leave the shortcut set to Booklet printing choices or other custom setups that are completely contrary to printing envelopes.  The least "best" choice is "Factory Defaults" - try to avoid that shortcut if you can do so.
