SOURCE: Printer printing out code and screen message is: HEX DUMP MODE

it may be that the settings for the printer is not ok, or probably the software to make the printer work was not installed properly. Try by uninstalling the application for the printer by going to control panel on your computer, then click on add/remove hardware, look for the printer application and uninstall it, restart your system again and reinstall back the application. Then check the settings made on your printer too, if you don't understand how to do that then go through the printer manual for further assistant, if the problem still persist , then take the printer to HP customer service center for configuration and setup. Thanks

SOURCE: how do I reset dcp-8045d hex dump mode

Probably the easiest way to turn off the Hex Dump mode would be to reset all printer settings. There should be a reset menu that will allow you to reset the printer to factory defaults. After which it should recognize the new ram and print normally.

How can I view my encrypted sync passwords on my mobile phone

Passwords are not saved on the phone. Sign ins on Android use a token system. You may possibly dump the memory with qpst and look for password with a hex editor, given you have access to diag mode and all drivers setup properly.

It states 'hex dump' on my printer and I don't know what it means

A hex dump is a list of hexadecimal numbers (base 16 numbers) of probably the contents of the memory.
This Hex dump is generated when the computer comes across a computer problem and can help Microsoft determine the cause and fix if this is sent to Microsoft.

I am sending raw data to the printer. Where to find ESC codes for different control ops


This feature allows experienced users to see exactly what data is
coming to the printer. This can be useful in finding software
problems. When you turn on the hex dump function, the printer
prints all commands and other data in hexadecimal format, along
with a guide section to help you find specific commands.
To use the hex dump feature, follow these steps:
1. After you make sure the printer is off, open the cover.
2. Hold down the FEED button while you turn on the printer.
3. Close the cover.
4. Run any software program that sends data to the printer. The
printer prints “Hexadecimal Dump” and then all the codes it
receives in a two-column format. The first column contains the
hexadecimal codes and the second column gives the ASCII
characters that correspond to the codes.
Hexadecimal Dump
1B 21 00 1B 26 02 40 40 . ! . . & . @ @
1B 25 01 1B 63 34 00 1B . % . . c4 . .
41 42 43 44 45 46 47 48 ABCDEFGH
❏ A period (.) is printed for each code that has no ASCII
❏ During the hex dump all commands except DLE EOT and
DLE ENQ are disabled.
5. Open the cover to set the printer off line, so that it will print the
last line.
6. Close the cover and turn off the printer or reset it to turn off the
hex dump mode.


Hope this helps u ..............

Hex Dump

Turn printer off. PRESS & HOLD PAUSE & FEED buttons after power goes out. While holding turn printer ON, count to 3 & let go. once printer does its checks press the MODE button 4 times to SAVE. the bottom 3 lights will flash 1 time. This should reset the entire printer including calibration, communications & everything to be like it just came out of the box.

I have a brady label machine 2461

Hex dump mode is mostly used for trouble shooting of the printer. To exit the hex dump mode, enter the Diagnostics menu / Hex
Dump Mode and select ‘Disable’. Exit the menu, save changes and
return to the ‘READY’ mode.
