Power On Modes

With the printer power on and top cover closed, press and hold the Feed button for several seconds. The green status LED will flash a number of times in sequence. The explanation at the right (Action) shows what happens when you release the key after the start specific number of flashes and before the next flash sequence starts.

Flash Sequence	Action
*	Configuration Status - Prints a detailed printer configuration status label. The label can be used
	to verify printing, assist printer to computer communication configuration, maintenance,
	troubleshooting, and help us with customer care communications.
	Standard Auto Media Calibration - The printer detects and sets media type and media length,
*	and it adjusts the media sensors for optimal performance with the installed media (equivalent ZPL
	command ~JC). The printer will feed one to four labels while calibrating.
**
	Note: Users familiar with the Zebra EPL desktop printer use this Feed mode to replace power-up
	AutoSensing calibration (equivalent EPL command XA).
	Serial Port Configuration - Applies only to printers with serial interface ports.
*	To reset the serial port communication parameters, except for Flow Control. Press and release the
	Feed button while the LED rapidly flashes amber and green.
**
	For autobaud synchronization: Send the ^XA^XZ command sequence to the printer while the LED
***
	rapidly flashes amber and green. When the printer and host are synchronized, the LED changes to
	solid green. NOTE: No labels will print during autobaud synchronization.
	Factory Defaults - Resets the printer to the factory default settings (equivalent to ZPL command
	^JUN). See Appendix: ZPL Configuration on page 109 for a description of the primary
	configuration settings and their associated ZPL commands. Some configuration settings are not
	returned to their initial ‘out of box’ settings. Other settings are exclusively set, viewed and
	controlled by programming are also reset. The performs a standard media calibration and then.a
*	memory defragmentation routine.
	Once the printer has entered the Factory Default mode, the status light will turn amber for
**
	three (3) seconds. During that time you may do two things: Do nothing and the printer will reset
***
	the factory defaults automatically as described above OR press and hold the feed button to enter a
****
	factory default reset modes for printers with a network (Ethernet, Wi-Fi or Bluetooth) printer
	option (equivalent ZPL command ^JUF). Releasing the button after the first flash resets the
	network factory options only (equivalent ZPL command ^JUN). Releasing the button after the
	second flash sequence (two flashes) will reset the printer defaults only. Releasing the button after
	the third flash sequence (three flashes) will reset both printer and network settings (equivalent
	ZPL commands ^JUN and ^JUF)
*	Print Width Adjustment - Prints a succession of boxes starting at the minimum print width and
	ending in the printer’s maximum print width in 4mm increments. Press the Feed button once when
**
	the printer has reached the desired maximum print width. Note that the printer driver and
***
	applications can override this setting.

*Print Darkness (Density) Adjustment - Prints a succession of bar code simulation patterns

**starting at the minimum darkness (print density/heat) and ending in the printer’s maximum darkness in increments of four (4) using the ZPL darkness setting range values. Press the Feed

***button once the pattern is clear and legible. Do not continue to increase the darkness setting or

****bar code line widths may become distorted reducing readability. Note that the printer driver and

*****applications can override this setting.

******

*Manual Media Calibration - The printer runs extensive tests to detect and set media type and

**media length, and then it adjusts the media sensors for optimal performance with the installed media (equivalent ZPL command ~JG). Manual calibration is recommended whenever you are

***using pre-printed media, print on the liner or if the printer will not correctly auto calibrate. A

****graphical profile of the media sensing will print. See Manual Calibration on page 92 for more

*****details and considerations.

If the Feed button remains pressed after 7th flash sequence cycle finishes, the printer exits the configuration mode when the Feed button is released.
