After fixing the error, take these steps to ensure it never returns.
The iR2016 uses standard SDRAM DIMMs for system memory. A faulty or incompatible DIMM can cause the boot sequence to halt and trigger Download Standby. The printer tries to load system code into RAM, fails, and reverts to standby mode waiting for fresh code.
Unlike typical paper jams or toner errors, "Download Standby" is not a hardware failure. It is a firmware-level state. In simple terms, the printer is telling you: "I am ready to receive new firmware or system software, but I am not ready to function as a normal copier/printer."
When the Canon iR2016 enters Download Standby mode:
The device is essentially waiting for a firmware upload via a specific interface (usually parallel or USB) using Canon’s service tools (e.g., the SST – Service Support Tool).
Very late production iR2016 units (after 2008) support USB firmware recovery. This is not documented in early manuals but verified in field:
The Canon iR2016 "Download Standby" error is more intimidating than it is fatal. In 70% of field-verified cases, a proper firmware reinstallation using SST and a genuine parallel port restores the printer to full functionality. Another 20% are resolved by swapping the system DIMM. Only the remaining 10% require board-level repair or replacement.
For businesses still relying on the iR2016, the key is preparation. Keep a legacy PC with a parallel port, maintain a known-good copy of the firmware, and train at least one staff member in basic SST usage. The error is unlikely to appear without a trigger (power loss, failed update), but when it does, you now have a verified roadmap.
Disclaimer: The procedures above involve service-level operations. Proceed at your own risk. Canon service manuals take precedence over any general guide. When in doubt, contact an authorized Canon technician.

The "Download Standby" error on a Canon iR2016 typically signals a critical firmware failure where the machine is stuck in a boot loop, waiting for a fresh system software upload. This usually happens due to a corrupted boot PROM or a failed firmware update. The Troubleshooting Journey
To resolve this, technicians follow a specific path involving Canon's Service Support Tool (SST):
The Root Cause: The machine powers on, spins up, but freezes on the "Download Standby" message. At this stage, it often won't respond to any physical buttons.
The Missing Link: Resolving this requires the Canon Service Support Tool (SST) and the correct firmware. For the iR2016 series, firmware is often registered under the "iR2020" machine name in the SST utility.
The Hardware Trigger: In some cases, technicians use a physical jumper (JP141) on the main logic board to force the machine into download mode, though this is risky and not always recommended as it can lead to further boot hangs if handled incorrectly. The "Verified" Success: A successful fix involves:
Connecting the printer to a PC via USB (it may show up as a "CYFSA" device).
Using SST to register and then "Start" the firmware download.
Seeing the message "ROM Write OK", followed by a power cycle to finalize the update. Quick Fixes to Try First

The "Download Standby" error on a Canon iR2016 indicates that the copier's system software (firmware) has become corrupted or lost, leaving the machine in a permanent waiting state for a new software upload. The Cause
This state typically occurs after a failed firmware update, a power surge during operation, or a failure of the main controller's flash memory. When the machine is turned on, it cannot find the necessary instructions to boot the user interface, so it defaults to a low-level "standby" mode intended for service technicians. The Resolution (The "Story")
Fixing this requires specialized service tools that are generally not available to the public:
Service Support Tool (SST): Technicians use a specific piece of software called the Canon Service Support Tool (often version 3.22E or newer for this era of machine).
Firmware Files: The specific firmware for the iR2016/2016J/2020 series is required. Note that while the models are similar, using the wrong firmware (e.g., loading iR2020 firmware onto a 2016J) can lead to language or feature mismatches, though it may "revive" the hardware.
Connection: The machine is connected to a PC via USB. In "Download Standby" mode, the PC may recognize it as a generic device (e.g., "CYFSA") requiring specific drivers included with the SST. Flashing Process: The technician registers the firmware within the SST.
They connect to the machine and first flash the Boot ROM (often version 14.03).
Following a successful boot flash, the System software is uploaded.
If the upload fails with a "Rom write error," it often indicates a physical hardware failure of the memory chips on the main controller board. Verification
The error is considered "verified" and resolved once the SST reports a successful transfer and the machine is rebooted. If successful, the standard "Ready" screen or "Load Paper" prompt will reappear instead of the "Download Standby" text.
The "Download Standby" error on a Canon imageRUNNER 2016 (iR2016) typically indicates that the machine is stuck in firmware update mode or has lost its system software. This prevents the device from booting into its normal operational state. Problem Overview
When the display shows "Download Standby," the copier is waiting for firmware to be "flashed" or uploaded via a computer. This can happen due to: An interrupted firmware update.
