A printer that feeds paper normally but outputs completely blank sheets can be highly confusing, especially if you have just installed fresh ink cartridges. On Kodak ESP and Hero printers, this symptom indicates a complete block in ink delivery — the print carriage is moving, but ink is not reaching the paper.
Here is a technician-guided troubleshooting path to restore ink flow.
Ink Flow Diagnostic Flowchart
Work through these diagnostic steps in order to identify where the block is occurring:
🔍 Ink Flow Troubleshooting Path
1. Check Cartridge Vents: Is the yellow protective tape removed? ➡️ If no, remove tape.
If yes, go to step 2.
2. Inspect Nozzle Plate: Blot the printhead bottom on a wet paper towel.
Does ink bleed out? ➡️ If no, perform a printhead soak. If yes, go to step 3.
3.
Check Electrical Contacts: Wipe the gold contacts on the back of the printhead. ➡️ Test print. If still blank, go to step 4.
4.
Inspect Purge Pump: Verify if the waste ink pump is operating and sucking ink during cleaning.
Fix 1: Check and Clear Cartridge Vent Holes
New ink cartridges have a protective plastic strip or tape covering the vent hole. If this tape is not removed, it creates a vacuum seal inside the cartridge, preventing ink from flowing out of the nozzle.
- Remove both ink cartridges from the printer.
- Look at the top of each cartridge. You will see a small vent hole (often near a yellow plastic pull-tab).
- Verify that the yellow tape has been **completely peeled away**. Even a small scrap of tape left over the vent hole will stop ink flow.
- If the vent hole looks blocked with plastic debris, gently clear it using a clean pin.
- Reinstall the cartridges and print a test page.
Fix 2: Blot-Test the Printhead Nozzles
If the cartridge vents are clear but pages are still blank, the printhead nozzles may have a solid plug of dried ink. You can perform a quick "blot test" to check:
- Remove the printhead from the printer carriage.
- Fold a clean paper towel. Dampen it slightly with distilled water.
- Gently press the bottom of the printhead (the nozzle plate) onto the wet paper towel and hold it for 3 seconds.
- Look at the paper towel: * **If you see two clear ink patterns** (black stripe and color stripes), ink is flowing through the printhead. The problem is electrical (Fix 3). * **If the towel remains clean or shows faint dots**, the printhead nozzles are clogged. Perform our printhead wet soak guide to clear them.
Fix 3: Clean Rear Printhead Circuit Contacts
If the printhead passes the blot test but still prints blank pages, the printer is failing to send print commands to the nozzles. This is caused by dirty copper circuit contacts.
- Remove the printhead block.
- Locate the gold contact pads on the back of the printhead.
- Wipe them firmly with a dry, lint-free microfiber cloth. Ensure no grease or ink residue remains.
- Reinstall the printhead, pressing until it clicks securely, and retest.
Fix 4: Check the Purge Pump Operation
Kodak printers use a vacuum pump to prime the nozzles and draw ink during cleaning cycles. If the purge tube is dislodged or blocked, the printer cannot prime the nozzles, resulting in blank pages.
- Look at the far right of the carriage path (the parking station where the carriage sits when idle).
- Locate the small rubber caps that seal against the printhead nozzles.
- Ensure these rubber caps are clean and not dislodged. If they are filled with dried ink, wipe them clean with a damp cloth to restore the vacuum seal.

Root Cause Analysis for Blank Page Output on Kodak Printers
When a Kodak printer feeds a sheet of paper through the engine, moves the carriage back and forth normally as if printing, but ejects a completely blank white sheet of paper, the mechanical paper transport and timing systems are working properly. The failure is completely isolated to the ink delivery subsystem:
the purge pump is not priming, the nozzle channels are air-locked, or the mainboard printhead driver circuit has blown a surface-mount pico-fuse.
Diagnostic Checklist & Recovery Steps
- Verify the Protective Yellow/Orange Tape is Removed:
Brand new Kodak ink cartridges feature a yellow or orange plastic pull-tab covering the air vent labyrinth on top of the cartridge. If this tape is not pulled off completely, a vacuum forms inside the cartridge as soon as the printhead fires, preventing ink from flowing out of the bottom nozzle port.
- Prime the Ink Delivery Channel (Removing Air Locks):
If you replaced cartridges after the previous set ran bone-dry, air bubbles become trapped inside the micro-fluidic channels. Run two consecutive Clean Printhead routines from the Maintenance menu to purge air locks.
- Inspect the Purge Pump & Capping Station:
Look at the far right side of the printer floor where the printhead parks. The rubber capping station must create an airtight seal over the nozzle plate for the suction pump to draw ink.
If the rubber seal is torn, coated in dried ink crust, or detached from its mounting spring, suction fails, resulting in unprimed nozzles and blank pages. Clean the rubber cap with a wet cotton swab.
- Check the Mainboard F1 / F2 Surface-Mount Fuse:
If all colors and black suddenly stopped printing simultaneously following an electrical surge or ink leak, the logic board's surface-mount protection fuse (labeled F1 or F2 near the carriage ribbon connector) has blown to protect the CPU from printhead shorts. A blown fuse requires board-level soldering or mainboard replacement.
Frequently Asked Questions
Why did my Kodak printer print one good page and then start printing blank pages?
This classic symptom occurs when the cartridge vent hole is partially blocked. The small amount of ink already sitting in the printhead chamber prints the first page, but the vacuum prevents fresh ink from entering the chamber for page two.
Can expired ink cartridges cause blank pages?
Yes. Expired ink cartridges (older than 2-3 years) can suffer from solvent evaporation through the plastic casing, causing the pigment to thicken into a high-viscosity sludge that the thermal heaters cannot atomize.
