Performing a pressure roller pressure test with simple tools is a practical way to ensure your equipment is operating within safe and effective parameters

Maintaining even roller pressure is essential in any application where material thickness and surface contact directly affect final product quality

You don’t need expensive equipment to get accurate results

With a few basic items you likely already have on hand, you can perform a reliable check

First, assemble the following items

A thin sheet of paper, such as 20 lb. printer paper, is ideal for خرابی غلطک پرس پرینتر capturing pressure impressions

You also need a ruler or measuring tape, a marker, and ideally a flat, clean surface to work on

Always power down and allow the rollers to reach room temperature before testing

Position both rollers so they make full, unimpeded contact along their entire length

Place the paper between the two rollers at the center point where pressure is most critical

Gently activate the rollers to simulate standard production conditions

Be sure to follow your machine’s standard operating procedure for engagement

Once the rollers have passed over the paper, stop the machine and carefully remove the paper

Look for the impression left by the rollers

A properly adjusted roller system will leave a consistent, unbroken line of compression

Inconsistent coloring or depth across the paper reveals pressure imbalances

Record the exact span of the compressed region using a calibrated measuring tool

Determine the difference between the original and compressed dimensions

The difference will tell you how much the paper was compressed

Conduct the test at least three times—left, middle, and right—to capture full roller performance

Keep a log of the compression values at each test point

A variance exceeding 10% signals potential misalignment or mechanical wear

Uneven pressure can cause print defects, material damage, or premature wear

In some cases, debris or worn bearings may be the cause

Wipe down rollers with a lint-free cloth and inspect for scratches, dents, or corrosion

Stick to one paper grade and weight to eliminate variability

Conduct tests in a controlled environment to minimize external influence

This technique provides both tangible data and immediate visual feedback on pressure consistency

While it doesn’t replace professional calibration tools, it’s an excellent routine check that can prevent costly downtime and improve product quality

Regular testing—once a week or before each major job—can extend the life of your equipment and keep your output consistent

If you notice persistent issues after multiple tests, consult your equipment manual or a trained technician

While this method reveals many issues, deep-seated mechanical faults need professional diagnosis
