Control Panel Password Reset HP M253

[Brian2705]

Just had a change of wifi router and need to reset the wifi password for the printer for my Laserjet M253. Due to a change in managent no one knows the Control Panel password. Does anyone know how I can factory reset the printer as it as the moment totally useless.

See the following steps from the Troubleshooting Manual for the M253.  NVRAM and COLD Reset can be used interchangably for this one.

NVRAM initialization
CAUTION: Be sure to print a conƭguration report before performing an NVRAM initialization.
An NVRAM initialization erases all data stored in the unprotected NVRAM sections. Performing an NVRAM

initialization resets the following settings and information:
-  All menu settings are reset to factory default values.
-  All localization settings, including language and country/region, are reset.

After performing an NVRAM initialization, reconƭgure any computers that print to this printer so that the
computers can recognize the printer.

1. Turn the printer off
2. Perform one of the following steps:
● 2-line control panels: Select and hold the right-arrow and the Cancel buttons simultaneously.
Keep them depressed as you turn the printer on.
● Touchscreen control panels: Turn the printer on, and then, as soon as the HP logo appears, press and hold the lower right quadrant of the control panel.
● M153-M154 LED control panels: Select and hold the Resume button. Keep it depressed as you turn the printer on and hold it for 20 seconds.
● M178-M181 LED control panels: Select and hold the up arrow and the Cancel buttons
simultaneously. Keep them depressed as you turn the printer on.
NOTE: It takes about 45 seconds before the NVRAM initialization process begins.

3. Perform one of the following steps:
● 2-line control panels: When the Permanent Storage Init. message appears on the display, release the right-arrow and the Cancel buttons.
● Touchscreen control panels: When the Permanent Storage Init. message appears on the display,  release the touchscreen.
● M153-M154 LED control panels: When the Ready LED turns on, release the Resume button.
● M178-M181 LED control panels: When the Ready LED turns on, release the up arrow and the Cancel buttons.
4. The NVRAM initialization starts.
5. When the printer has ƭnished the NVRAM initialization, it returns to the Ready state.

Super NVRAM initialization
A super NVRAM initialization restores the printer to the “generic printer mode” in which it arrived from the factory. This means that you will have to reset the language and country/region settings when the printer starts after the initialization. A super NVRAM initialization erases all data stored in the protected and unprotected NVRAM sections.
1. Turn the printer off.
2. Perform one of the following steps:
● 2-line control panels: Select and hold the left-arrow and the Cancel simultaneously. Keep them depressed as you turn the printer on.
● Touchscreen control panels: Turn the printer on, and then, as soon as the HP logo appears, press and hold the lower left quadrant of the control panel.
● M153-M154 LED control panels: Select and hold the Resume button. Keep it depressed as you turn the printer on and hold it for 40 seconds.
● M178-M181 LED control panels: Select and hold the down arrow and the Cancel buttons simultaneously. Keep them depressed as you turn the printer on.
NOTE: It takes about 45 seconds before the super NVRAM initialization process begins.
3. Perform one of the following steps:
● 2-line control panels: When the Permanent Storage Init. message appears on the display, release the left-arrow and the Cancel buttons.
● Touchscreen control panels: When the Permanent Storage Init. message appears on the display, release the touchscreen.
● M153-M154 LED control panels: When the Attention LED turns on, release the Resume button.
● M178-M181 LED control panels: When the Attention LED turns on, release the down arrow and the Cancel buttons.
4. The super NVRAM initialization starts.
5. When the super NVRAM initialization completes, the printer enters the generic printer mode.
