What Is Epson Error Code 000043?

Epson error code 000043 is a Paper Feed (PF) PID Reverse Error that occurs when the printer detects abnormal movement in the paper feed mechanism. The issue is usually caused by a paper jam, dirty PF encoder, damaged gears, faulty paper feed motor, or a malfunctioning encoder sensor. Epson service documentation associates this code with reverse or abnormal PF motor feedback rather than a simple paper jam.

Unlike a normal paper jam notification, Error 000043 indicates that the printer’s internal control system detects incorrect paper feed movement or receives unexpected feedback from the PF encoder.

To protect the mechanism from further damage, the printer immediately stops operation. Epson service documentation associates this code with reverse or abnormal PF motor feedback rather than a simple paper jam.

Understanding the PF PID Reverse Error

The term PF PID Reverse Error may sound technical, but it simply describes a mismatch between the paper feed motor’s expected movement and the movement detected by the printer.

Think of it like a car’s GPS.

If your GPS expects you to drive forward but detects you’re moving backward, it immediately flags an error.

Your Epson printer works similarly.

The printer constantly monitors:

Paper feed motor rotation
Encoder feedback
Feed roller movement
Gear synchronization

If these components become misaligned or stop moving correctly, the printer generates Error Code 000043 to prevent further damage.

Common Causes of Epson Error Code 000043

Although the error message is the same across many Epson printer models, the underlying cause can vary.

The table below summarizes the most common causes and their impact.

Cause	Severity	DIY Fix Possible?
Hidden paper jam	Low	✅ Yes
Dirty PF encoder disc	Medium	✅ Yes
Dust on encoder sensor	Medium	✅ Yes
Worn paper feed rollers	Medium	Sometimes
Broken paper feed gears	High	No
Faulty PF motor	High	No
Loose encoder cable	Medium	Yes (if accessible)
Main board failure	Very High	No

Service manuals and repair references consistently identify paper-feed obstruction, contaminated PF encoder scales, damaged encoder cables, PF motor faults, and main board failures as the primary causes of Error 000043.

1. Hidden Paper Jam

The most common cause is a small piece of paper trapped inside the printer.

Many users remove visible paper but overlook tiny torn pieces lodged deep within the paper path.

Common locations include:

Behind the feed rollers
Near the duplex unit
Under the carriage assembly
Around the rear access door

Even a small paper fragment can prevent the paper feed mechanism from rotating normally and trigger Error 000043.

In the next part, we’ll cover a detailed step-by-step troubleshooting workflow, advanced diagnostics for the PF encoder and motor, model-specific tips, and preventive maintenance to help you resolve the error efficiently.

2. Dirty or Contaminated PF Encoder Disc

The PF (Paper Feed) encoder disc is a transparent plastic disc with fine markings that allows the printer to monitor the paper feed motor’s rotation accurately. If dust, ink mist, grease, or fingerprints cover the disc, the encoder sensor cannot read the markings correctly.

When this happens, the printer assumes the paper feed mechanism is not moving as expected and triggers Epson error code 000043.

Common Symptoms

Error appears immediately after powering on.
Printer starts feeding paper, then stops.
Grinding or clicking noises during startup.
No visible paper jam.

How to Inspect the Encoder Disc

Turn off the printer and unplug the power cable.
Open the printer cover carefully.
Locate the paper feed motor area (model-specific location).
Identify the transparent encoder disc attached to the motor shaft.
Check for:
- Dust buildup
- Ink splashes
- Fingerprints
- Scratches
- Cracks

Cleaning Tips

Use a lint-free microfiber cloth.
Lightly dampen the cloth with isopropyl alcohol (90% or higher).
Gently wipe both sides of the encoder disc.
Allow it to dry completely before reassembling the printer.

Expert Tip: Never use paper towels or abrasive cloths. Even tiny scratches on the encoder disc can affect the sensor’s accuracy.

3. Dirty or Misaligned Encoder Sensor

The encoder sensor works with the encoder disc to track the paper feed motor’s movement. If the sensor becomes dusty or shifts out of position, it may misread the encoder markings.

Signs of a Faulty Encoder Sensor

Random paper feed errors
Printer works intermittently
Error appears after transportation
Cleaning the encoder disc doesn’t resolve the issue

What to Check

Dust inside the sensor slot
Loose sensor mounting screws
Damaged wiring
Bent sensor bracket

Cleaning the sensor with compressed air or a soft brush often resolves minor issues.

4. Paper Feed Roller Problems

Feed rollers grip and move the paper through the printer. Over time, these rubber rollers wear out, become smooth, or collect dust.

When the rollers lose traction, the paper may slip or fail to feed correctly, leading the printer to detect abnormal paper feed movement.

Symptoms of Worn Rollers

Multiple sheets feeding at once
Paper slips without moving
Skewed paper alignment
Frequent paper feed errors

How to Clean Feed Rollers

Turn off the printer.
Remove all paper from the tray.
Rotate each roller manually.
Clean with a lint-free cloth lightly dampened with water.
Allow the rollers to dry before testing.

If the rubber is cracked or excessively smooth, replacement is recommended.

5. Damaged Paper Feed Gears

The paper feed mechanism relies on a series of plastic gears to transfer motion from the motor to the rollers.

If even one gear is cracked, worn, or missing teeth, synchronization is lost, resulting in Error Code 000043.

Warning Signs

Loud clicking noises
Grinding sounds
Feed rollers stop rotating
Printer jams repeatedly
Error occurs immediately during startup

Can You Repair It Yourself?

Replacing paper feed gears usually requires:

Complete printer disassembly
Gear alignment
Timing calibration
Specialized tools

For most users, professional repair is the safer option.

6. Faulty Paper Feed (PF) Motor

The PF motor powers the paper feed mechanism. If it becomes weak, overheats, or fails electrically, the printer can no longer control paper movement accurately.

Common PF Motor Symptoms

Motor hums but doesn’t rotate
No paper movement
Burning smell
Repeated startup failures
Persistent Error 000043 after cleaning

DIY Check

Without opening the motor:

Listen for unusual noises.
Observe whether the rollers attempt to rotate.
Check if the motor starts and stops abruptly.

A failed motor generally requires replacement.

7. Loose or Damaged Encoder Cable

The encoder sensor communicates with the printer’s main board through a delicate ribbon cable.

A loose or damaged cable can interrupt communication, causing incorrect encoder readings.

Inspect the Cable For

Loose connectors
Torn ribbon
Pinched wiring
Corrosion
Burn marks

Reconnect loose cables carefully. If the ribbon is damaged, replace it with a compatible part.

8. Main Board Failure

Although less common, a faulty main board can also generate Error 000043.

The main board processes signals from:

PF motor
Encoder sensor
Carriage motor
Various printer sensors

If the board cannot interpret these signals correctly, it may incorrectly report a PF error.

Possible Indicators

Multiple unrelated error codes
Printer won’t initialize
No motor activity
Burn marks on the board
Previous power surge or liquid damage

Main board replacement should only be performed by trained technicians.
