Fix jams with recycled paper — check grain direction, moisture content & paper type (HP, Epson, Canon, Brother, Xerox)

Technician

Hey! Let’s stop those recycled paper jams. Tell me your brand — HP, Canon, Brother, Epson, Xerox — and the paper size, GSM/weight, and whether the reams were acclimated to room humidity. Also, do the sheets feel wavy or curled? That points to moisture content and grain direction issues.

Customer

We’re using recycled 80 gsm A4. The printer is a HP LaserJet. It keeps jamming at the pickup rollers and sometimes in the fuser. The paper looks a little wavy, especially on humid days.

Technician

Thanks — classic signs of high humidity + wrong grain direction with recycled stock. Recycled paper can have slightly shorter fibers and higher moisture absorption. If the paper grain is running the wrong way for your tray, sheets resist bending around rollers and stall near the registration or fuser.
Quick plan: 1) verify grain long vs grain short, 2) acclimate and store the ream, 3) match paper type in the driver (Plain/Thick/Recycled), and 4) clean/replace pickup rollers if glazed.

Customer

How do we check the grain direction? The wrapper doesn’t say.

Technician

Two quick grain tests
• Fold test: Tear a strip both directions. The tear that’s straighter/cleaner runs with the grain.
• Curl test: Slightly moisten one corner; paper curls toward the grain as it dries.
For most laser printers with long paper paths, use grain long (GL) in portrait trays so sheets bend smoothly around rollers. If jams happen after the duplex unit or into the fuser, try a ream with grain short (GS) to reduce buckle on tight turns.

Customer

The office is pretty humid. We store open reams in a cupboard. Could that cause the wavy paper jams?

Technician

Definitely. Keep paper at 40–55% RH and 20–24 °C. Open reams absorb moisture, causing edge wave, curl, and multi‑sheet feed.
• Store reams sealed in the wrapper and flat on a shelf, not on the floor.
• Acclimate unopened reams for 24–48 hrs in the print room before use.
• If a ream feels damp, re‑wrap it with desiccant and let it rest, or use a dehumidifier near the device.
• For recycled stock, pick laser‑certified recycled paper with consistent moisture control.

Customer

What driver settings should we change for recycled paper?

Technician

In the print dialog and on the printer’s panel set:
• Paper Type/Media: choose Recycled or Plain; if jams continue, try Thick 1 / Heavy to slow the fuser speed.
• Tray setting: match the exact size, weight (80–90 gsm), and grain if listed.
• Duplex: if duplexing increases curl, test single‑sided or flip binding. Curl after the fuser often signals moisture or wrong paper type.

Customer

We’ve cleaned the path a bit. How do we know if the pickup rollers are the problem vs the paper?

Technician

Load a small stack of fresh non‑recycled paper from a sealed ream. If jams disappear, the issue is the recycled stock (moisture/grain). If jams persist, inspect pickup/retard rollers for glazing. Clean with a lint‑free cloth and isopropyl alcohol; replace if shiny or below spec. Also fan the stack and don’t overfill the tray — multi‑feeds trigger “jam at registration” errors.

Customer

We also print on an Epson inkjet. Any differences with recycled paper there?

Technician

Inkjet uses a straighter path but recycled stock may cockle with heavy ink. Choose Inkjet paper or Multi‑purpose that’s inkjet‑compatible. In the driver pick Plain or Matte, reduce ink density, and avoid the damp ream. Proper paper storage matters for inkjet too.

Customer

We run duplex booklets. After long runs the stack curls and jams near the finisher. Any fix?

Technician

Use a low‑curl setting (Heavy/Thick) to slow the fuser, load the stack curl down, and rotate the ream 180°. For recycled stock, consider 90–100 gsm or a ColorLok/laser‑certified recycled grade. Keep runs short and let the stack cool and condition.

Customer

Any tips for choosing recycled paper that won’t jam?

Technician

Buying checklist — recycled paper for laser & inkjet
• Look for laser‑certified recycled (ISO 9706/9707 or manufacturer approval).
• Target 80–90 gsm, smoothness ≥ 160 Sheffield for laser; higher grams for duplex booklets.
• Confirm grain long for portrait trays (or match your device spec).
• Moisture‑controlled packaging with sealed reams and date codes.
• Buy from one lot number for color‑critical jobs to keep caliper consistent.

Customer

Got it. We’ll test grain long, store sealed reams, and change the media type. Hopefully that ends the recycled paper jams.

Technician

Summary: Most jams with recycled paper trace to humidity, grain direction, or media mismatch. Store sealed reams, verify grain long vs grain short, pick the correct paper type (Recycled/Thick), and keep rollers clean. Want hands‑on help picking the right stock for your model?

Quick answer: the accepted fix

Accepted fix when recycled paper is causing jams: store reams sealed and acclimate to 40–55% RH, use the correct grain direction, set the driver’s paper type to Recycled/Thick to slow fuser speed, and match tray size/GSM. If jams persist, test a fresh sealed ream and clean or replace pickup rollers.

FAQ

Step‑by‑step (diagnose jams on any OS)

1. Load 20 sheets from a sealed ream and test. If jams stop, the recycled stock is the issue.
2. Verify grain direction with the tear test; rotate the stack if needed.
3. Set driver Media Type to Recycled/Thick and match size/GSM; clean pickup rollers.
4. Control environment: 40–55% RH, sealed storage, and acclimation for 24–48 hrs.

Step‑by‑step (store & acclimate paper)

1. Keep unopened reams in original moisture‑barrier wrap, flat on shelves.
2. Move reams to the print room 24–48 hrs before use to acclimate.
3. After opening, re‑seal with tape; add desiccant in humid climates.
