Canon Service Tool V3400: Fix Error 5B00, P07 & Ink Absorber Full
Your trusted Canon desktop printer has abruptly halted mid-operation. The power and alarm LEDs blink in an alternating sequence (typically 7 cycles), while your computer screen flashes the dreaded notification: "Error 5B00," "Error P07," or "The ink absorber is full." Before assuming your hardware has suffered a fatal breakdown, understand that this is purely an internal software safety lockout. Here is the verified diagnostic walkthrough and factory-grade utility—Canon Service Tool V3400—to successfully enter Service Mode, reset your EEPROM counter, and restore full printing functionality in under five minutes.
Understanding Error 5B00, P07 & The Software Lock
Canon inkjet printers—ranging from the legendary PIXMA iP2770 and MP287 workhorses to early G-Series tank models (G1000, G2000, G3000)—employ an internal sponge assembly known as the waste ink absorber pad. During printhead cleaning cycles, initial ink priming, and borderless margin flushes, discarded micro-droplets are redirected into these pads.
To avert potential ink overflow onto desks or internal motherboards, Canon's firmware logs every droplet via an EEPROM mathematical counter. When this counter registers 100% saturation, the printer instantly halts all functions:
- Error 5B00: The standard Windows driver notification signifying complete ink absorber capacity lockout.
- Error P07: Displayed on 7-segment LED multi-function printer panels (such as the MP287).
- 7 Alternating Blinks: Physical indicator LEDs cycling Orange (Alarm) and Green (Power) alternately 7 consecutive times before pausing.
This barrier is not mechanical. In practically all home and office workflows, the physical felt pads retain substantial absorption buffer. By resetting the firmware EEPROM counter back to 0% with Service Tool V3400, your machine will resume normal high-speed operation immediately.

Pre-Flight Setup & Requirements
- Direct USB Connection Only: Service Mode communicates across low-level port hooks. Disconnect Wi-Fi and use a dedicated USB cable directly to a motherboard rear port (avoid USB hubs).
- Rear Paper Tray Loaded: Insert 2 to 3 sheets of standard A4 paper. Upon completing the counter clear, the printer automatically executes an EEPROM test print.
- Single Printer Active: Clear all pending print jobs from the Windows Print Queue and unplug any other connected printers to avoid communication collision.
Step-by-Step Canon Reset Procedure
Canon printers require a physical button handshake to unlock communication. Follow these steps methodically in exact sequence.
Enter Service Mode (The Critical Handshake)
Do not launch the software yet. You must force the printer motherboard into its low-level diagnostics mode using physical hardware buttons:
- Turn the printer OFF, but leave the AC power cable firmly plugged into the wall.
- Press and HOLD the Resume / Cancel button (marked with an orange inverted triangle inside a circle).
- While continuing to hold Resume, press and HOLD the Power button (green LED lights up).
- Continue holding the Power button, but RELEASE the Resume button.
- While still holding Power, press the Resume button firmly exactly 5 TIMES. The indicator LED will toggle between Orange and Green with each tap.
- Release ALL buttons simultaneously.
Verification Check: The green Power LED will blink for several seconds while internal mechanisms cycle. Wait patiently until the green light turns SOLID (stops blinking completely). If the light remains solid green, your machine is successfully in Service Mode. If it blinks continuously or flashes orange, turn off the printer and repeat Step 1.
Prepare USB Link & Extract Utility
Once the green light is solid, Windows will detect new hardware (often appearing as "CanonDevice" or an unfamiliar composite USB printer in Device Manager).
- Ensure the USB data cable is securely seated between the printer and your PC.
- Confirm that at least 2 sheets of blank A4 paper are loaded into the rear paper feeder.
- Right-click the downloaded
Canon_Service_Tool_V3400.zipfile and choose Extract All.
Launch Service Tool as Administrator
Navigate to the unzipped folder, right-click Service Tool V3400.exe, and select "Run as administrator."
If your printer is correctly established in Service Mode, the program interface will launch with all input fields, buttons, and drop-down menus fully active (not grayed out).
Configure "Clear Ink Counter" Parameters
Inspect the right-hand panel of the Service Tool window to locate the Clear Ink Counter section:
- Absorber: Click the drop-down menu and select
Main(orMain & Platenif available for your multi-function model). - Counter Value (%): Confirm the value is set to
0%.
Execute EEPROM Flash & Verify Test Print
Click the "Set" button positioned immediately next to the Clear Ink Counter field.
The printer will immediately engage its carriage assembly and print a single line of diagnostic code across your loaded A4 paper, reading:
D=000.0
Simultaneously, Windows will present a dialog box stating: "A function was finished." Click OK to confirm that the EEPROM register has been rewritten to zero.
Power Cycle & Return to Normal Operation
To complete the initialization and commit the cleared EEPROM state:
- Close the Canon Service Tool V3400 utility window.
- Press the printer's Power button to turn it completely OFF. (Wait until all mechanical sounds cease and the green light turns off entirely).
- Wait 10 seconds, then press the Power button to turn the printer back ON.
Success: The printer will power up normally with a solid, calm green LED. Error 5B00 / P07 is eradicated, and your printer is ready for everyday production.
Troubleshooting: Resolving Error 006
The most common stumbling block during a Canon reset is Error Code 006 (Communication Error), where the utility freezes or alerts that the printer cannot be accessed. Here is how to fix it:
Printer Not in True Service Mode
If the green LED was still blinking or if you tapped Resume 4 times instead of 5, the motherboard is not ready. Shut down completely and redo Step 1 until the green light is 100% solid.
USB 3.0 Port Incompatibility
The legacy communication protocols inside Service Tool V3400 often fail on modern blue USB 3.0 / 3.1 ports. Plug your USB cable into a black USB 2.0 port located on the back of your desktop PC.
Conflicting Driver Instances
When entering Service Mode, Windows sometimes generates a duplicate printer driver (e.g., "Canon iP2700 Series (Copy 1)"). Ensure print queues are purged and disconnect other printing hardware.
Clearing the software counter resolves the firmware blockade, but the actual physical waste ink still accumulates inside the bottom felt reservoirs. If your printer has logged over 15,000 pages or has undergone multiple counter resets:
- Periodic Pad Cleansing: Disassemble the outer casing, remove the porous felt sponges, wash thoroughly under warm water until clear, and allow to dry 100% before reinstalling.
- External Waste Tank Mod: For high-volume print shops using CISS or continuous tank conversions, reroute the internal purge pump hose to an external waste ink bottle to prevent leakage permanently.
