Canon MG8150 Touchscreen Service Mode
Canon service mode is not one universal button combination. This page isolates touchscreen Cancel-area method with five presses for MG8150 and separates the button sequence from the later waste-counter reset.
Touchscreen Cancel-Area Method With Five Presses
MG8150 uses a touchscreen area rather than a normal physical Resume/Cancel key during the sequence.
MG8150 uses a touchscreen area rather than a normal physical Resume/Cancel key during the sequence.
The number of STOP, RESET, Cancel or touchscreen presses is not a decorative detail. It selects a printer mode. The correct sequence must be completed before Wic Reset Connect can access the supported waste-ink counter.
Service-mode detection and the protected reset should not use Wi-Fi or a hub.
The activation key is entered only after the printer stays visible in Wic Reset Connect.
Touchscreen cancel-area method with five presses is the defining sequence for this page.

Service mode is used for a supported counter reset
Use the workflow for supported waste-ink messages such as 1700, 5B00, 5B01 or 5B02. Cartridge, print-head, scanner, paper-feed and mechanical errors need separate diagnosis.
A nearby model can use a different number of presses.
HOME, Resume or Cancel may be an invisible screen area during startup.
Never use an activation key to test whether service mode worked.
Software cannot stop a real ink leak or repair a saturated part.
Why the printer does not enter the expected mode
Most failed attempts come from a wrong count, an early POWER release, a misidentified touchscreen area or unstable USB detection.
Touching the screen after it has gone dark without knowing the button area
Stop, power the printer off completely and repeat the exact documented sequence. Confirm stable USB detection before continuing.
Skipping the five-to-ten-second wait
Stop, power the printer off completely and repeat the exact documented sequence. Confirm stable USB detection before continuing.
Using six presses from the general MG table
Stop, power the printer off completely and repeat the exact documented sequence. Confirm stable USB detection before continuing.
Removing USB during Windows enumeration
Stop, power the printer off completely and repeat the exact documented sequence. Confirm stable USB detection before continuing.
Service mode first, Wic Reset Connect second
After the printer enters the correct mode, connect it directly to Windows, select the detected model in Wic Reset Connect and paste one purchased activation key. Keep POWER and USB stable until the final program message.
Use the key only after stable service-mode detection
Windows should keep the Canon device visible and the power indicator should remain stable. Alternating green and orange lights normally point to another active error or an incorrect mode.
Canon MG8150 Touchscreen Service Mode FAQ
Which Canon printers use touchscreen Cancel-area method with five presses?
This page covers MG8150. Always compare the complete model with the current service-mode table before pressing buttons.
When should the USB cable be connected?
Use a direct data connection and wait for Windows to detect the service device before opening Wic Reset Connect.
Does service mode reset the waste counter by itself?
No. Service mode only prepares the printer. Wic Reset Connect and one activation key perform the supported counter reset.
How do I know the press count was registered?
The printer should stop normal booting, remain detected by Windows and show the expected stable indicator rather than an alternating error pattern.
Can I repeat the button sequence?
Yes, but first turn the printer off completely and wait a few seconds. Do not repeat it while the printer is still in another mode.
Can I use Wi-Fi?
No. Use direct USB for service-mode detection and the protected reset.
What if the printer has a touchscreen?
Use the documented screen area that corresponds to HOME, Resume or Cancel. A dark display can still have an active touch area.
Why should I not guess between five and six presses?
The count selects a mode. The wrong count can start another maintenance function or leave the printer unavailable to Connect.
What errors are normally related to the reset?
Supported Canon waste-ink warnings include 1700, 5B00, 5B01 and 5B02. Other faults must be diagnosed separately.
Does the software repair a full absorber?
No. It changes the supported electronic counter. A saturated or leaking absorber still needs physical service.
Does an unused key expire while I prepare service mode?
No. An unused key has no expiry date before use.
Where is the current Canon service-mode reference?
Use the official page at https://wicresetconnect.com/en/canon-service-mode/ and confirm the exact model group.
Confirm the method, connect by USB and reset once
Use the official service-mode table, verify stable detection and then complete the supported waste-counter reset with Wic Reset Connect and one activation key.
