Hi my name is ***** ***** I will be the expert working with you today to help and resolve the problem you have posted.
I am sorry to know that you are facing problem with your printer.
when do you hear screechy noise and does it pick paper or goes to paper jam any error.
Please explain the problem a bit more in detail.
Open the printer cover and remove the cartridges and then slide the print head at the extreme left hand side of the printer. Use a flash light and check for any paper or debris inside do remove the paper tray and check the inside. Use a compressed air to blow inside and then close the cover and unplug the power cable and leaave the printer for 5 mins.
do you have machine oil or lubricant? Use a ear but wet it and apply it on the belt inside area make sure you do not apply too much as it will drip and will damage your printed papers.
The product needs servicing from inside which is not done by end user. If the product is under warranty then you can get it serviced from authorised Epson service center for free or else there will be a nominal charge for the servicing.
