Why Printer Prints Lines or Faded Output and How to Fix It?

If your printer is producing lines on the page or faded prints, it can be frustrating—especially when you need clear documents. This is a common printer issue faced by both home and office users. The good news is that most causes are easy to identify and, in many cases, simple to fix.

Understanding why your printer prints lines or faded output helps you take the right action and restore print quality quickly.

Common Reasons for Lines or Faded Printing

Several factors can affect print quality. Below are the most common causes:

Low Ink or Toner Levels

• Ink or toner is running low
• Cartridge not distributing ink evenly
• Toner powder clumping inside the cartridge

When ink or toner levels are low, prints often appear faded or show missing lines.

Clogged or Dirty Print Heads (Inkjet Printers)

• Dried ink blocking nozzles
• Dust buildup on print heads
• Irregular ink flow

Clogged print heads can cause horizontal or vertical lines and uneven colour output.

Worn-Out Drum or Toner Cartridge (Laser Printers)

• Drum unit reaching end of life
• Scratched or damaged drum surface
• Toner not transferring evenly

This often results in repeated lines or faded areas on every page.

Incorrect Print Settings

• Printer set to draft or economy mode
• Low-resolution print quality selected
• Wrong paper type chosen

Incorrect settings can reduce ink usage, causing light or streaky prints.

Dirty Rollers or Internal Components

• Dust or paper residue inside the printer
• Toner buildup on internal parts
• Paper feed contamination

Internal dirt can affect how ink or toner is applied to the paper.

How to Fix Lines or Faded Output

Once you identify the cause, you can apply the right solution:

Check and Replace Ink or Toner

• Check ink or toner levels
• Replace empty or low cartridges
• Gently shake toner cartridges to redistribute toner (if recommended by the manufacturer)

This is often the quickest fix for faded prints.

Clean the Print Head

• Use the printer’s built-in cleaning option
• Run print head alignment after cleaning
• Avoid manual cleaning unless recommended

Regular print head cleaning improves ink flow and print clarity.

Adjust Printer Settings

• Change print quality to “High” or “Best”
• Disable draft or economy mode
• Select the correct paper type

Proper settings ensure optimal ink or toner usage.

Inspect and Replace Worn Parts

• Check drum units in laser printers
• Replace damaged or old components
• Follow manufacturer replacement guidelines

Replacing worn parts restores consistent print quality.

Perform Regular Printer Maintenance

• Clean rollers and internal areas
• Keep the printer dust-free
• Use good-quality paper

Maintenance prevents recurring print quality issues.

When to Call a Professional

If the problem continues even after basic troubleshooting, professional help may be needed.

Seek Expert Help If:

• Printer shows error messages
• Internal parts need replacement
