This article aims to deal with common faults of the K1 series flagship model. For details of the K2 series, please see: Error Code Summary for K2 Plus Multi-color Printer

Ⅰ. 506 Error Trouble Shooting

1. Problem description

After printing started, the screen popped up "key:506, AI LiDAR calibration failed", as shown below:

506 Error Trouble Shooting

2. Reason analysis

There are foreign objects or damaged wrinkles on the calibration sticker.
The surface of the AI module lens is not clean.
The height difference between the calibration plate and the hot bed platform on the same horizontal plane is large.
The AI lidar is abnormal.

3. Troubleshooting and solution

Clean or replace calibration stickers.
Clean the surface of the AI module lens.
Adjust the height of the calibration plate.
Replace the AI module.

Ⅱ. 2000 Error Trouble Shooting

1. Phenomenon description

The printer screen pops up "key:2000, unknown exception" prompt, as shown below:

2000 Error Trouble Shooting

2. Cause analysis

The main board and the nozzle board suddenly lost communication.
Internal error, need to get the log to locate the problem.

3.Troubleshooting and solution

Remove the nozzle cover and replug the nozzle connection cable. If it cannot be solved after plugging and unplugging, replace the nozzle connection cable.
Export logs to the developer for analysis.

Ⅲ. 2001 Error Trouble Shooting

1. Phenomenon description

The printer screen pops up "key:2001, unknown exception" prompt, as shown below:

2001 Error Trouble Shooting

2. Cause analysis

Main thread error, program crashed.
Internal error, need to get the log to locate the problem.

3.Troubleshooting and solution

Restart the machine.
Export logs to the developer for analysis.

Ⅳ. 2111 Error Trouble Shooting

1. Phenomenon description

The printer screen pops up "key:2111, unknown exception" prompt, as shown below:

2111 Error Trouble Shooting

2. Cause analysis

It is because the nozzle extrusion temperature is less than 170°C for three main reasons:

Sliced file error.
Nozzle heating anomaly.
Gcode has an extrusion order for less than 170°C.

3.Troubleshooting and solution

3.1 Sliced file header error

Use the official slicing software Creality Print, the slicing version number in V4.3.5 and above, select the corresponding slicing model, prohibit the selection of other models of slicing.

3.2 Nozzle heating anomaly

If there is no problem checking the document, exit the printing interface and heat the nozzle separately.
If 2507 or 2564 appears, please check the [2564 Error Trouble Shooting].

3.3 Gcode has an extrusion order for less than 170°C.

Use the official slicing software Creality Print, the slicing version number in V4.3.5 and above, select the corresponding slicing model, prohibit the selection of other models of slicing.

Ⅴ. 2505 Error Trouble Shooting

1. Phenomenon description

The printer screen pops up "key:2505, Motor drive exception" prompt, as shown below:

2505 Error Trouble Shooting

2. Cause analysis

The main board fan bolt is against the main board X-axis driver on heat dissipation block, and long-term contact causes damage to the drive chip.

2504 Error Trouble Shooting

Driver chip virtual soldering.

2504 Error Trouble Shooting

3.Troubleshooting and solution

Contact official customer service or after-sales processing.

Ⅵ. 2564 Error Trouble Shooting

1. Phenomenon description

The printer screen pops up "key:2564, extruder not heating as expected" prompt, as shown below:

2564 Error Trouble Shooting

2. Cause analysis

The thermal terminal wire is not plugged in when the nozzle is heated.
The ceramic heating block/thermal wire of the nozzle is loose or not tightly inserted.
Broken or cracked solder joints on the wires of the ceramic heating ring at the hot end.
The thermal on the nozzle is loose.

3.Troubleshooting and solution

Open the nozzle cover, and then check whether the nozzle heating wire and thermal terminal block on the nozzle board are inserted in place, and also check whether the terminal is inserted in place.
Remove the nozzle insulation sleeve and check for any other abnormal conditions such as cracks on the ceramic heating ring.
The thermal on the nozzle is loose.
Please contact Official Customer Service/After-sales to Replace Nozzle Kit.

2564 Error Trouble Shooting

The serrated shape can only be solved by replacing the thermal or hot end

Ⅶ. 2565 Error Trouble Shooting

1. Phenomenon description

The printer screen pops up "key:2565, the heated bed is not heating as expected" prompt, as shown below:

2565 Error Trouble Shooting

2. Cause analysis

The hot bed fuse is damaged.
Hot Bed Power cable Open Circuit.

3.Troubleshooting and solution

Remove the bottom cover.
Check the wiring on the hot bed plate and refasten it.
If you don't have a professional multimeter measuring tool, skip this step. If you have a professional multimeter measuring tool to measure whether the voltage output on the adjusting plate is normal or if the voltage measurement is abnormal, contact customer service/after-sales service to replace the heating bed board.
Please contact the official customer / after-sales service for replacement of the hot bed plate kit.

Ⅷ. 3002 Error Trouble Shooting

1. Phenomenon description

The printer screen pops up "key:3002" prompt.

2. Cause analysis

The nozzle drag chain cable is abnormal or the terminal connection (the port number on main board: J51 ) is loose.
The drag cable of the leveling plate is abnormal or the terminal connection (end number: J11 on the mainboard) is loose.
The firmware of the upper computer does not match the firmware version of the lower computer, etc.
Main board is abnormal

3.Troubleshooting and solution

Replace the nozzle drag chain cable or re-plug the terminal.
Replace the leveling drag chain cable or re-plug the terminal.
Upgrade firmware.
Replace the main board

Ⅸ. 2509 Error Trouble Shooting

1. Phenomenon description

The printer screen pops up "key:2509, Sensor temperature exception" prompt, as shown below:
2509 Error Trouble Shooting

2.Cause analysis

Thermistor issue.
Thermosensitive filament is damaged or not properly inserted.
Hotend board issue.

3.Troubleshooting and Solution

Check if the thermosensitive wiring is loose/damaged/broken.
Replug the thermosensitive ribbon cable.
Re-insert nozzle kit.
After checking the above steps, if the problem still cannot be solved, please contact after-sales service cs@creality.com.
