Epson CX4800 in scan mode

Scanning at resolutions greater than 200 dpi causes an error message that says the computer cannot communicate with the scanner. This happens after some time into the scan. Epson is on USB 2.0.

There are also times, when printing, that the PC gets impatient with the HP laser printer, and messages that the document did not print, but it is still printing. HP is on ECP Centronics port.

I suspect that there is a timeout somewhere, but I don't know what to change. This is a home-built PC: ASUS mobo with AMD 2 GHz Athlon 64 X2, 667 MHz memory, XP Home Edition SP2.

The scan problem is lesser (I can use a higher resolution) when using a slower HP laptop.

Hi jacobdani!

Good to know you downloaded the driver. If you would do something for me: Go to Epson's website and download their driver for the CX4800. This driver may be updated on the website from yours. Also, see if there is a new firmware for your printer. If there is, download that as well. If you say that connections are fine, then the cables shouldn't be the problem. Good luck and let me know how you did!

Not sure how you're removing the driver, but if you go to control panel device manager remove the printer totally as an option; reboot and then reload the printer. You also need to identify the remote printer in the print sequence or as your default printer in set-up (device manager). Hope this helps.

if the unit is directly connected via USB, another program or prev installed scanner software is using "the path" to communicate with the scanner. Can only use one scanner at a time with windows.

I have printer plus scanner epson l200. and I thought there is option for scanning a film. but it turned out the option is greyed out. I wonder if this type is available for scanning film or there is

To scan film, your scanner needs a light above the film. Not just a light, but a calibrated light. That is why the scanners who can scan film and transparent sheets, have a lit with a light in it. Your scanner does not have this, so scanning film is not possible. One of the cheapest (flat bed) scanners from Epson is the V600 and costs about $200, Epson Perfection V600 Photo Scanner

When I try to scan, I get "memory full"

Try scanning at a lower resolution. Scanning an A4 Photo on highest resolution is likely to give the printer a memory meltdown causing the Memory Full message.

Scan at 1200x1200 DPI instead of 1200x2400 DPI. Depending on what you are using the scan for you can even bring it down further. if it is just to facebook or e-mail pictures then 600x600 is fine.

I have used last 4 year canon 2900B printer. How to set 300 dpi printing resoluation

Canon PIXMA Manuals MG2900 series Resolution
Resolution The data in the image you have scanned is a collection of dots carrying information about brightness and color. The density of these dots is called "resolution", and resolution will determine the amount of detail your image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.5 cm). The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less detail.

How to Set the Resolution You can set the resolution in Resolution on the (Scanning from a Computer) tab of the Settings dialog.
Appropriate Resolution Settings Set the resolution according to the use of the scanned image.
Item Type Use Color Mode Appropriate Resolution Color photo Copying
(Printing) Color 300 dpi Creating a postcard Color 300 dpi Saving to a computer Color 300 dpi Using on a website or attaching to e-mail Color 150 dpi Black and white photo Saving to a computer Grayscale 300 dpi Using on a website or attaching to e-mail Grayscale 150 dpi Text document (document or magazine) Copying Color, Grayscale, or Black and White 300 dpi Attaching to e-mail Color, Grayscale, or Black and White 150 dpi Scanning text using OCR Color or Grayscale 300 dpi Important
  • If you double the resolution, the data size of the scanned image quadruples. If the file is too large, the processing speed will slow down significantly, and you will experience inconvenience such as lack of memory. Set the minimum required resolution according to the use of the image.
  • When you will be printing the scanned image by enlarging it, scan by setting a higher resolution than the recommended one above.

You received a cd for the all in one. After Installing the CX4800, you should see an Epson Scan Icon on your desktop. Double click it open, then you should see this. Click on Scan and there you go.
Good Luck.

Scanning files to large

It's the resolution you are using to scan. Try a lower setting. for documents, 150-200 dpi is fine. That will produce smaller files.
