Cleaning the print head is an important process that contributes to the quality of the printed objects. It reduces the risk of clogging and ensures even extrusion of the filament.

Cleaning the nozzle from the outside

● We recommend that the outer tip of the print head (the nozzle) daily with the cleaning tool included in the accessory box.

Allow the print head to cool down first. Scrape the nozzle with the cleaning tool until the tip is free of filament residue. Make sure that you do not touch the inductive sensor (blue dot) behind the nozzle when cleaning it.

Cleaning the inside of the nozzle

● We recommend cleaning the inside of the nozzle every time a new filament spool is loaded. Only use approved cleaning filament for this process.

Proceed as follows:

1	Open the menu Filament changeby pressing the settings button (1).
2	Heating up. Please wait until the target temperature has been reached.
3	Pull the old filament out of the extruder and press the WfurtherButton (2).
4	Select Yes (1).
5	Heating up. Please wait until the target temperature has been reached.
6	Feed the cleaning filament into the extruder. When the filament comes out of the nozzle, press the Further-button (2)
7	In this automatic step, the temperature begins to drop as the material is extruded. Note: You may hear a clicking noise. This is normal.
8	In this automatic step, the extrusion is switched off and the print head is cooled down.
9	Remove the extruded filament from under the nozzle.
10	Turn the lever to idle / position 0 (anti-clockwise).
11	Grasp the cleaning filament and pull it out of the extruder.
12	Clean any burnt residue from the nozzle using the brush supplied.  Attention! The nozzle temperature is 110 degrees!
13	Look through the nozzle. You should be able to see through the hole.
14	Turn the lever clockwise to position 3 and then insert new filament.
15	Wait until the print head has heated up.
16	Insert the regular filament and when the material comes out of the nozzle, press the confirmation button (1) to complete the process.

To ensure that the printer continues to print as expected, regular cleaning is recommended. Both the print bed and the print head must be cleaned.

System information about the printer can be found in the information menu. This is usually used for customer support.
1	Open the menu Settingsby pressing the settings button (1).
2	Open the menu Printer information and firmware updateby pressing the Information button (1). Press the Back button (2) to return to the main menu.
3	The information screen shows the following (1): The printer modelThe unique name of the printer.BIOS version of the printer.Printer firmware version. Press the Back button (2) to return to the Settings to return.

If required, it is possible to control the movement and heating of the printer manually.

1	Open the menu Manual controlby pressing the manual control button (1).
2	Use the arrows (1) to move the print head in the working area. Press the home button in the centre (1) to move all axes to their "home" position (zero). Move the print bed up and down using the Z-axis arrows (2). Extrude or retract the filament with the print head control arrows (3). (Note that these buttons are deactivated if the print head temperature (5) is lower than the target temperature (6)) Start manual heating with the temperatures (5 and 6). When manual heating is started (the printer holds or reaches a certain temperature), the button  a red border. If no manual heating is activated, the border is green.
3	Set the target temperature by pressing the down arrow (1) and the up arrow (4). To confirm the target temperature and start heating, press the confirmation button (7). The status of the heating controller is shown on the display (6), which shows IDLE when not heating and HEATING when heating. In addition, the lighting in the printer is white when the heating control is switched off and purple when the control is switched on. To stop heating, either go back to the main menu or reduce the target temperature (3) below 30 oC ("-" is displayed) and click on Confirm (7) Press the Back button (5) to return to the menu Manual control to return to the main menu. Press the Back button (5) again to return to the main menu.

Printing via WLAN is started directly from the GP Inlay Print module in the GP Manager and the file is automatically transferred to the printer's internal memory.

1
	Open the GP Inlay Print module and select the relevant job from the job list. Select a page. Check whether a printer in the printer list on the left-hand side is idle (IDLE). Make sure that the printer is prepared for printing. See chapter 10. Start printing via the button Start printing via WiFi. The printer indicates that printing is being started via Wi-Fi.
2	The print preview screen shows the status of the print process during printing: (1) indicates whether the printer is heating or printing. (2) shows the current and target temperature. (3) shows the remaining time of the print job to be completed. (4) shows whether printing has been started via WiFi. (5) shows the progress of the print in %. (7) shows the file name of the object to be printed. To pause printing, press the pause button (8). For more information, see section 11.3. To cancel the printing process, press the cancel button (6).
