Enter service mode
Keep this page on hold until the exact model-specific sequence is confirmed.
Reset and restart
Run WIC Reset Connect, keep USB stable, then switch the printer off for at least 10 seconds before normal startup.
Before using a key: the printer must have no pending jobs or unrelated errors. Use one direct USB connection and leave only the target Canon Pro9500II connected.
Understand the warning
Why Canon Pro9500II shows errors 5B00–5B04 or 1700
The Canon professional photo printer estimates how much waste ink has been collected during cleaning and maintenance. When the programmed limit is reached, the printer may display 1700 as an advance warning or stop with 5B00 and a waste ink absorber message. The reset clears that electronic counter; it does not fix an unrelated print-head, cartridge or power fault.
For this Canon model, WIC Reset Connect performs the counter operation after service mode is accepted. Do not enter the Connect key into WIC Reset Utility. Disconnect other Epson and Canon equipment, keep only the Pro9500II attached and wait for a clear success message before restarting.
Official developer
Use the official WIC Reset Connect download and a key intended for this workflow, with technical support available if the program returns an error.
Reset guarantee
Keep the program message and order details if a valid attempt fails. A failed attempt can be reviewed instead of repeating random steps.
No pre-use expiry
An unused activation key does not expire. One key is consumed by one completed reset on one supported printer.
Resettable Canon absorber codes: on supported models, WIC Reset Connect can clear the waste ink counter behind Canon support codes 5B00, 5B01, 5B02, 5B03 and 5B04. The exact code displayed depends on the printer and region.
Physical maintenance still matters: software resets the electronic counter only. If ink is leaking or the absorber/pads are saturated, clean or replace the maintenance components before continued printing.
Step-by-step procedure
How to put Canon Pro9500II into service mode
Canon service-mode sequences vary by printer series, control panel and regional model. Do not guess the number of button presses or copy a sequence from a similar printer. Use the Canon service-mode guide below and choose the method that matches your exact model or series.
Prepare the Canon Pro9500II
Turn the printer off, leave power connected, clear pending print jobs and connect it directly to a Windows computer with a USB data cable. Disconnect other Canon and Epson devices.
Open the Canon service-mode guide
Check the model and series in the complete WIC Reset guide. It explains the POWER, STOP/RESET, HOME or touchscreen combinations used by different Canon families.
Follow the matching sequence exactly
Use only the method shown for your printer family. Count every press carefully, release the buttons in the stated order and wait until the printer finishes entering maintenance mode.
Check detection before using a key
The printer should settle without an unrelated flashing error and Windows should detect the service-mode device. Only then open WIC Reset Connect and start the counter reset.
You can also use the complete Canon reset manual. If the printer does not enter service mode, switch it off, unplug it for 10–15 seconds and repeat the correct model-family method.
Requirements and common mistakes
Prepare the Canon Pro9500II before activation
Required setup
- Windows 7, 8, 10 or 11 computer.
- Direct USB data cable connected without a hub or splitter.
- Only the target Canon Pro9500II connected; remove other Epson or Canon equipment.
- No pending print documents and no unrelated printer error.
- Stable power for the complete reset and restart.
- Correct model-specific service mode before opening Connect.
Avoid these failed attempts
- Do not use Wi-Fi or a network-only connection.
- Do not enter a Connect key into WIC Reset Utility.
- Do not disconnect USB or power while the program is writing.
- Do not confuse a waste ink warning with a print-head or cartridge failure.
- Do not repeat head cleaning unnecessarily after the reset.
- Save the complete message or log before asking for support.
You can also open the video instruction library or verify another model in the supported printer finder.
Troubleshooting
If the Canon Pro9500II reset does not start
Printer is not detected
Change to a direct motherboard USB port, remove hubs, try another data-capable cable and disconnect other Canon or Epson devices. Restart Windows if the maintenance device was not installed correctly.
The printer still shows another error
Write down the exact code and check cartridges, paper path and power status. WIC Reset Connect cannot bypass an unrelated fault that prevents the printer from reaching the required maintenance state.
The connection stopped during reset
Do not repeatedly reuse random software or button combinations. Save the log, screenshot and key details. If a valid attempt was interrupted, use the replacement-key request or contact support.
Warning returns after restart
Confirm that the program reported success and that the printer was switched off for about 10 seconds. Check the exact counter or error again rather than assuming every service message is the waste ink counter.
